Is evolution inevitable?

Can a species avoid evolution for thousands of years? If, for example, there is no need to evolve or change like crocodiles and alligators ?

So that was the major question. Now for the second, minor question that I am wondering about. Sooo some people think that bigfoot exists but what if "bigfoot" is unevolved...like maybe it somehow avoided evolution somehow?

nice answers plz? thank u all in advance :)

    There are 'living fossils" such as the coelacath that have been unchanged for long periods of time. It's due to they being adapted to their environment and the environment not changing.

    The 'Bigfoot" existence is unlikely. Ten million years ago there was a giant ape, Gigantopithecus that would seem to meet the requirements for a "Bigfoot" ancestor.. However, the ape lived in SW China and died out some 300,000 years ago.

    To be "Bigfoot" the ape would have had to migrant to the Americas and survive. That's not likely.

    The major problem with "Bigfoot" is having a viable population. The brown bear lives in much similar environments and eats many of the same things "Bigfoot" would. There's some 700,000 brown bears in North America. They are so plentiful that hunting is allowed.

    The problem with "Bigfoot" is that to have a viable population, we'd have many more encounters. Last summer we took a bus trip and saw 3 bear inside of an hour. Bear get hunted and shot, bear get trapped, bear get hit by cars. However, not "Bigfoot."

    Certainly it's possible that Gigantopithecus made it to the Americas, survived and evolved into "Bigfoot." However, we don't have the bodies. A viable population, or even a shrinking one would still provided specimens. However the last "Real Bigfoot body" turned out to be a rubber suit in a freezer.

    Actually, Icabod, it is silly to assume that bigfoot is an "ape". Most sightings report that they look more human than ape.

    There are gigantopithecus fossils that date to approximately 100 thousand years ago. Based on the scarcity of the fossil record, that doesn't mean they died off then. It only means that it is the most recent fossil.

    We have much more recent fossils of Homo erectus some of which apparently lived to at least 20 thousand years ago. Some Homo heidelbergensis were nearly 8 feet tall assuming proportionate skeletons. Some Homo erectus were so large that they were called meganthropus. I have scaled up the skeleton and found it was also 8 feet tall assuming a proportional skull to height.

    All animals must have evolved for their particular niche and each stage of evolution must also have been an animal that was well suited to its environment. Bigfoot wouldn't have avoided evolution. There is no evolutionary goal for animals to become like us. Perhaps bigfoot shared a recent common ancestor a couple million years ago but moved into a colder environment where size was favored. Obviously the size would help it cope with predators.

    I do not think so, for evolution not to occur is like saying nothing is going to change. Most causes of evolution is a sudden change in environment or climate, but even when this is not the case, there is a big chance of mutation happening during the forming of a new descendant.

    Remember evolution does not move in the same direction for the same species. If there is a bigfoot, it does not mean he did not evolve, it just mean he is another branch of the same tree.
