-This weeks movie was Kevin Reynolds' Waterworld (1995) starring Kevin Costner, Jeanne Tripplehorn, and Dennis Hopper. IMDb Link: http://www.imdb.com/title/tt0114898/?ref_=nv_sr_1

-What a strange movie. This was thought to make loads of money, but ended up flopping at the theaters and for good reason. This movie takes place in the future world where the polar ice caps melt and send the world into a huge you guessed it, water world. The Mariner, Kevin Costner, must rescue an orphan girl who will lead them to the "dryland" which is like the only piece of earth that isn't water. Along the way he faces people trying to kidnap her and take the dryland for themselves. This movie was not the greatest. 4/10.

-Evolutionary, it wasn't great either. I didn't mention before, but the Mariner has developed gills in order to swim without going up for air. We run into the same problem we had with the X-men. The Mariner is in fact a mutant, but he developed the gills based on need. One is simply not able to adapt based on need, as Dobzhansky said, "Natural selection is a blind, yet creative process." The gills would have had to randomly mutate before his actual need for them. This is a Lamarkian idea. He proposed that giraffe's necks were originally short and grew in length in order to reach the leaves high above them. This was proved wrong many many years ago, but Hollywood somehow missed the memo. We won't see any gills mostly likely on anyone very soon, unless you are Harry Potter and live in a magical world where evolution does not exist.
-I recently watched Marc Forster's World War Z (2013) starring Brad Pitt, Mireille Enos, and Daniella Kertesz. The IMDb link is here: http://www.imdb.com/title/tt0816711/?ref_=nv_sr_1

-This movie follows a man during the brink of total world collapse as a zombie pandemic attacks the entire world. He goes across the entire world trying to find a cure. He ends up injecting himself with a deadly pathogen, which keeps the zombies from attacking him since they only go for a healthy host. Although slightly far-fetched, this movie was very entertaining. I enjoyed the scene where he injects himself with the serum and walks face to face with the zombie and essentially walks through the entire facility unscathed. He uses a soda machine to bring all the zombies to him and walks right through them. Entertaining movie. 7/10

-Now for the evolutionary side of this movie. The movie faces the traditional "can zombies happen?" question. This movie has zombies that have un-human-like strength and speed. There is no way for a person to come back from the dead, however, like in the case of rabies, it could be transmitted to another host. This is very interesting to me and I did some research. So the zombies in the movie are attacking others so the virus will have another host. There exists a parasite called Toxoplasma gondii that infects mice and has to be inside cats to reproduce. It works by making mice not afraid of cats so they will be eaten and therefore be able to reproduce. However, this is a parasite and a virus could be less likely to have this effect in humans. The zombies themselves are very intelligent. They are able to discern who is infected and who is not infected. That is very difficult for even a doctor who is not infected to discern. This would mean that the virus somehow gave them a special ability which is just not possible. The incubation time of the virus, (which is in the ballpark of 10 seconds in the movie) is unrealistic. Hold onto your pants, zombies won't be invading the world. Hopefully.

-Just watched: Matthew Vaughn's X-men First Class (2011) starring James McAvoy, Micheal Fassbender, and Jennifer Lawrence. the IMDb link can be found here: http://www.imdb.com/title/tt1270798/?ref_=nv_sr_4

-Finally the X-men origin story we've all been waiting for. This was a solid movie chronicling the beginning of Xavier and Erik's friendship (AKA Professor X and Magneto). This movie was very entertaining and it was neat to see the mutants in another time period. The special effects have also come along way since the first X-men movie in 2001. The fighting scenes were very cool and the dialogue was well-scripted. You got what you ask for in this superhero movie. My favorite scene was when Magneto killed Shaw by forcing the Nazi coin into his brain. Great movie. 7/10 stars.

-X-men movies however hold little wait from an evolutionary aspect. For starters, most mutations are deleterious rather than beneficial. Almost every single on of the mutants possess an ability that helps rather than harms them. But first, I will address a character that is not scientifically accurate, which is odd considering his name is Darwin. His mutation allows him to adapt to any circumstance that he needs, ie he can grow gills to breathe under water. His adaptions are somewhat reminiscent of "survival of the fittest" which is not a Darwinian idea. The whole idea of mutants is actually a Lamarckian idea. The ability for an individual to develop mutations beneficial to them, the classic giraffe growing his neck to reach branches idea. We find this to be false because giraffes with long necks had better fitness than those with shorter necks and were able to survive. Another constraint of natural selection is gene variation. If the gene for say changing skin color like Mystique is not present in the population, it cannot pop up randomly. Unfortunately or fortunately, we will not see a Magneto-like mutant in our population. So no world domination due to mutants in the future.

-I recently watched Stanley Kubrick's classic 2001: A Space Odyssey (1968) starring Keir Dullea, Gary Lockwood, and William Sylvester. Click below for a link of the IMDb page. http://www.imdb.com/title/tt0062622/?ref_=nv_sr_3 

-This movie follows several astronauts as they journey to Jupiter to discover a "monolith" that mysteriously popped up. Along the journey, there is a problem however, when their A.I. robot turns on them and leaves one stranded in space. Eventually, the main character shuts down the system and is able to escpape. The ship goes through a worm hole and aliens show him the beginning of life and eventually he is turned back into an embryo. This movie is a strange one. The best part of the movie to me is the memorable music. Bad special effects and lack of dialogue left a bad taste in my mouth. 5/10 stars.

-Although not your typical evolution movie, it does hold some evolutionary concepts in it. At the beginning, it shows 2 groups of apes. After the monolith appears on Earth, one group learns to use bones as weapons. This group is able to hunt better and has higher fitness. Although not entirely true, this is actually how natural selection works to an extent. Another scene sticks out to me. the very ending, the human "devolved" back into an embryo. Once again, alien technology has never been tested, but it goes out of the constraints of evolution for a human to revert to its embryonic form. However, this reminded me of an organism that essentially does this exact process. Turritopus dohrnii, or the immortal jellyfish has a process similar to this. The jellyfish start as larvae then gives rise to polyps that are on the sea floor. They then bud off and become sexually mature. Then, if the jellyfish experiences an environmental stress, or becomes sick or old, it can go back to the polyp stage and essentially repeat the entire process. It would be interesting to understand how the creature is able to do this from an evolution standpoint. Although this is very interesting, humans will most likely never be able to revert to their embryonic state once reaching maturity.

-This week I looked at John Carpenter's The Thing (1982) starring Kurt Russell, Wilford Brimley, and Keith David. IMDb link: http://www.imdb.com/title/tt0084787/?ref_=nv_sr_1

-This movie kept you on the edge of your seats. Although made in the early 80s, it was still enjoyable to watch despite the special effects that weren't so special. There was an eeriness about the whole movie like you didn't know who you could trust. My favorite part in the movie is when the doctor goes to use the defibrillator on Norris and his stomach turns into 2 jaws and bites his arms off. The monsters are very corny, put the movie on the whole is good. It got a very high rating on IMDb and for good reason. Very enjoyable movie that I would watch again. 8/10.

-The science in the Thing is almost non-existant. They devolop a theory throughout the movie that the thousands of year old aliens learn to "imitate" other organisms. This starts with a dog. The alien somehow coats its body with one of a sled dog. At one point the scientist claims that the alien "learned" to digest things. How could the alien ever consume anything if there was no digestion? Also, digestion is too complicated of a process to spring spontaneously, see conditions for Natural Selection proposed by Darwin. Whenever provoked, it broke its way out of the dog body and began showing its true form... which changes throughout the movie. Each alien is different than the one before it. Aliens have not been study in full in real life, but there must be a type of order amongst species. Each organism would most likely at least resemble other organisms within that species. Soon the aliens start imitating humans. I'm not an alien expert, but I have never seen a terrestrial organism that can completely coat its outward body into something that resembles a human. I've heard of camouflage and coloration in animals, but never a completely different skin. This movie will most likely never become a reality. If it somehow were able to, we would be in deep deep trouble.
-Finished Dawn of the Planet of the Apes (2014) starring Gary Oldman, Keri Russell, and Andy Serkis. The link the IMDb page can be found here. http://www.imdb.com/title/tt2103281/?ref_=fn_al_tt_4

-This entertaining movie is a continuing movie in a rebooted series about genetically evolved apes that threaten the human race after a super simian flu wipes out most of the civilization. I thoroughly enjoyed this movie more than the originals or even the other reboot. There was a lot of action and well-done CGI. My favorite scene was when two apes fooled humans into pretending they were dumb and killed them and took their weapons. 8/10.

-Now to address the scientific side behind the movie. It is interesting how they approached the speech aspect of the apes in this movie. Most movies just assume that apes can learn to speak out of nowhere and run with that idea. In this movie, speech is looked at a little differently. In the beginning, the apes are pretty non-vocal and speak in grunts. They first learn sign language. And something neat that I didn't realize is that the younger apes can learn sign language easier than the older apes. This is interesting and how humans typically learn. The apes in this movie were extremely smart and were able to learn and adapt to behavior. As I mentioned earlier, the apes were able to understand that if they walked like apes, then they weren't seen as harmful, but if they acted like humans they posed a threat. I am no expert, but it might take some time before we see apes leading a revolution to overthrow humans.

-Just watched Peter Weir's Master and Commander: The Far Side of the World (2003) starring Russell Crowe and Paul Bettany. A link to the IMDb page can be found here: http://www.imdb.com/title/tt0311113/?ref_=nv_sr_1

-This movie was very entertaining. This movie followed the HMS Surprise during the Napoleonic Wars in pursuit of a powerful French warship. It is full of action, but has several slow scenes. It definitely portrays sailor life during the 1800s. My favorite scene is when Paul Bettany's character removes a bullet from his own abdomen using a mirror as a guide. It was an interesting scene because it demonstrates the sterility of sail boats during the time and the risk for infection. I thoroughly enjoyed the movie. 8/10.

-This is not a typical movie one would consider to talk about evolution in. However, there is a character, played by Paul Bettany, who is a physician and a naturalist that greatly resembles Charles Darwin. This movie takes place in the South American seas and islands. One island in particular is the Galapagos islands. While the majority of the crew is interested in fighting and defending the ship, he is more interested in studying specimen on the islands. There is a scene where the crew is having target practice and he is studying a beetle that was found near the island. While discussing adaptations in organisms, a boy asks him if God caused the changes in the specimen in which he replied that God could have done that or he caused them to change. This reminded me of Dobzhansky and I found that very interesting that they would incorporate that into this movie. In one scene, he is describing how an insect uses camouflage to disguise itself from predators. The captain then camouflages the ship to hid from their "predator." It is interesting that this movie would incorporate a Darwin-like character into an action movie. It shows the impact that Darwin had on the world.

-I recently watched Ridley Scott's fan-favorite classic Alien (1979) starring Sigourney Weaver and John Hurt. A link to the IMDb page can be found here: http://www.imdb.com/title/tt0078748/?ref_=nv_sr_2

-This movie revolutionized the horror and "A.I." genre in movies. Although I believe it was a little bit before its time, this movie was very entertaining. Had I watched this movie maybe 25 years ago, the horror aspect would have been more prominent. Today's movies are far scarier so therefore it was not as frightening as it would have been to someone in the 80s. A spaceship in deep space that is used for mining is under attack by an alien. Sigourney Weaver is a lone survivor, along with a cat, as she struggles to survive. The aliens evolve while on board. My favorite scene in this movie was when the alien popped out of John Hurts stomach. It was very gruesome and portrayed the nastiness of the alien. 8/10.

-This movie, although entertaining, does not have much scientific background. Alien movies are able to push the limits of normal thinking, because there is not definite evidence in order to study. This way, film makers have a bit of lee way when creating movies and don't have to follow scientific thinking as much as normal. However, there are still constraints to evolution that were ignored in this movie. The alien, which starts off as a small creature smaller than an average house cat manages to grow to larger than a human in a short span. There are many reasons why this is not possible, firstly with the physiological constraint. The amount of food that would have to be consumed is astronomical to have it grow that much that fast. Natural selection can be a fast moving process, but within one generation, this is not possible. Such a simple creature over the course of a few hours grows up to 10 times its size. It would be interesting if specimen were able to grow exponentially like this, but I'm afraid that the big screen stretches the truth at times.

-This week, I watched Ron Underwood's Tremors (1990) starring Kevin Bacon and Fred Ward. A link to the IMDb page can be found here: http://www.imdb.com/title/tt0100814/?ref_=nv_sr_1

-This was an extremely ridiculous movie that exemplifies the late 80s and early 90s. "Graboids" attack the town and its up to 2 ridiculous Nevada cowboys to take care of these blind and tooth-filled creatures. This movie was comedic simply based on the ridiculousness of the movie. A cameo by Reba McEntire makes the whole film worth it in my opinion. My favorite scene is the ending when the graboid plummets to its death off the cliff. Tremors really captures old 50's monster movies. 5/10 stars.

-On to the science side of this film. These creatures known as graboids, is a fictional species of sand worm that is blind and lives underground. These creatures can move incredibly fast through the sand and use echolocation to  determine where it is. Not much thought was put into the name of these creatures because their tentacles "grab" its prey and bring it in. They have a reptilian appearance although they are worm and have tentacles. These creatures do not resemble any creature I have ever seen. Scientifically could they exist? I'm not too sure. They are said to weigh 10-20 tons. yet they are able to burrow faster than humans can run. Their diet consists of humans and cattle, and they would also need to eat quite a few calories to fuel their metabolism. But, they are unable to differentiate between the things they are eating, so they eat everything and then spit up whatever is not edible. This is not a very good evolutionary system. Tremors does not try to explain the creatures, but simply states that they are there. I was interested into how echolocation worked after watching this movie. It is an incredible process. I am however curious to how it would work while underground.
-This past week I watched Gareth Edward's Godzilla (2014) starring Bryan Cranston and Aaron Taylor-Johnson. A link to the IMDb page for this movie can be found here: http://www.imdb.com/title/tt0831387/?ref_=nv_sr_1

-This was a pretty entertaining movie.. when Godzilla was actually on the screen.
The majority of the movie is dialogue on how to stop the invading monsters, and then Godzilla makes cameos. It was a little different than other Godzilla movies in that this monster actually helped more than destroyed. Also Bryan Cranston dies way too early in the movie which is strange considering he's a top billed cast. My favorite scene is near the very end of the movie whenever Godzilla rips open one of the other creature's mouth and spits blue fire into the other creature's body, killing it. All in all, the movie was not terrific, but you got what you want with a monster movie. 6/10 stars.

-Now for the scientific side of this movie. Lets start with the basics of the monster. The movie alludes that Godzilla was formed from massive amounts of radiation to komodo dragons living in the pacific. This movie suggests that since the 1940s, one komodo dragon was able to grow extremely high. I was actually curious how tall Godzilla was actually supposed to be. He is suggested to be 355 feet tall. Which is impossible for the dimensions of this creature. It's legs far too skinny to support such massive height and weight. Godzilla supposedly weighs 90,000 tons... He would need 215 million calories in order to survive daily. The amount of food required to sustain his metabolism is impossible to consume. Now back to the radiation. There's no doubt that atomic bombs can cause genetic mutations. This was clearly seen after the Hiroshima and Nagasaki bombings following WWII. But, it is not possible for a komodo dragon to grow hundreds of feet and thousands of pounds in just a few generations. Another thing to keep in mind is that there are physical constrains on natural selection. The trait must exist in an organisms gene pool in order for it to be mutated. This is the reason humans cannot have mutations like the X-men. I was curious to how radiation actually affects future generations. Further research would be interesting. But I'm certain that we won't be seeing a 355 foot tall monster destroying any cities anytime soon.

Evolution (2001)

This was a very comical movie that kept you laughing throughout the fictional plot. The basic premise of the movie is that a meteor crashes in a desert and lands in an underground cavern. After taking samples, they determine that its an extraterrestrial being that evolves very fast. This is pretty much where the science ends. They discover that the aliens evolve extremely fast and develop traits that were not already introduced into the genome. The first organisms they discover resemble flat worms and reproduce exponentially through mitosis. These organisms reproduce very fast, much faster than possible in real life. They are viewing one worm under a microscope and then another guy goes to view the worm and it already split into around 4 worms. This is a highly unlikely speed of reproduction. After returning to the cave only the next day, they find that the flat worms are also surrounded by fungi. One of the constraints on natural selection proposed by Darwin states that the trait that will be changed must already be in the organism. Or simply, a human could never produce claws like Wolverine, or shoot lasers from your eyes like Cyclops from the X-men comic. therefore, these round worms could not evolve so quickly into a different type organism. Soon, after returning to the cave, they find it teeming with life that resembles a rainforest. They discover that all the aleins are unable to breathe oxygen and is lethal to them. Soon, there are dinosaur-like creatures that are able to fly, but as one enters the oxygen, she dies, but as she dies she spits out an egg that hatches into another  alien dinosaur that is able to breathe oxygen. This almost supports a Lamarack idea that a trait influenced by the environment can be passed on to the next generation. This process would be much slower, but due to the increased evolutionary characteristics these aliens have, it makes sense that this would happen so fast. Eventually, the army steps in and ignites all the aliens with napalm. They then all combine to form a super large creature that resembles a giant flat worm. This creature is so large and would not be able to function metabolically. It would be unable to take in the amount of food necessary for all the metabolic reactions necessary for survival. They determine that the worm is most likely poisonous to selenium which is found in Head and Shoulders shampoo. They then in a funny way kill the alien with Head and Shoulders and save the day. In conclusion, the movie was entertaining, but did not show much scientific thought. The evolutions depicted in the movie were unlikely, and the mutations occurred extremely fast, almost never skipping a generation.
