Natural Selection

Video 1: The Barnalce Beast
In this video this animals had to do a difficult thing that was falling 120 meters in the air to continue their life as birds, if they survived they followed their mom and dad and move on, so this relates to the natural selection theme because the birds that didn't have the skills or characteristics needed for that fall didn't survive and the ones who did have the abilities and strengths were the ones that survived. There are many more species like this that have to make a big sacrifice to keep the species better.

Video 7: Kangaroo
Since the baby Kangaroos are born it's their responsibility to train and learn how to fight for years so that they have the respect of the clan and have the chance to be the big champion, and win all the female Kangaroos in the clan, so that only that Kangaroo can have offspring and the species keeps on evolving on the best way possible. This is also an example of Natural selection because the best offspring with the best abilities can be the winner and the others would be the losers and won't get any female to reproduce.

Poster Evolution Project

                                        Past:
Resultado de imagen para Acinonyx KurteniAlmost 5.5 million years ago the great Acinonyx Kurteni lived, a big carnivore animal with strong bones and muscles. Very similar to the Cheetah, bigger muscles big head, jaw and paws to grab their prey stronger and kill them almost inmediately.



Present:
The Average Cheetah has changed from the Acinonyx Kurteni by decreasing the muscle and bone volume, the Cheetah now has the ability to run incredible speeds in very short time, now the Cheetah is very agile and has developed more strength on its feet so he can run and catch their prey fast and quickly. It's sight and hearing has increased too because the Cheetah needs to be silent while he gets close to the prey and also needs to see from long distances to see if there are many animals that may defend from his attack.

                             Future:
Resultado de imagen para black cheetahThe Cheetah will be all black with no spots, he will develop bigger and stronger claws for climbing steap mountains, he will have better eye sight to look far away for other prey and will change his diet to brown bears that live there and will hunt mostly deers. He will recover some of the volume and strength in his legs for giving strong hits to the prey and getting quickly to it.
