because its environment changed
Yes, but they would need to be very alert as there are many other species that are extremely harmful to North American animals.
No
The animal who doesn't adapt will die..that means the animal who was strong enough to handle it's environment breeds with another animal that was strong enough to handle it's environment. That results in offspring with the same strong qualities and it continues evermore.
No
Probably some of them (example:crocodile). The crocodile is a modern species of what use to be a prehistoric creature. The species would adapt based on the environment due to natural selection. just to expand on that the croc has remained unchanged since the time of the dinosaurs,
I think the two things for population of species if they do not adapt. The answer I think is sea turtles,and salmon.
Evolution is always happening. Species are constantly changing to adapt to their surroundings. If evolution wasn't always happening, many different species would have died.
well the animals adapt to their surroundings when they go there when they do not adapt they tend to find another place to adapt to
It would either adapt to another habitat or become extinct.
It's not that they must. The ones that adapt survive. The ones that don't die out.
The theory of evolution posited the theory that species gradually adapt to their environment. The theory claims that humans were originally apes.
A species with a diverse gene pool are less threatened by environmental change because at least one form of the species would probably be able to adapt better than another form which would probably die out. while a species without a diverse gene pool could possibly die out if it was unable to adapt to the environmental change.
