Is it possible for exotic animals to survive in a different environment?

Answer

Dear Enis,

Actually, I have to answer your question in two ways. One answer is about whether animals can adapt to a temperature, the other answer is about evolution.

I’ll start with the latter. The evolution of species happens, among other things, through natural selection. That means that some animals of a certain species will be better adapted to the temperature in which they live (to stick with your example). Those best adapted animals will live longer on average, find the best partners, reproduce the best,… and so there are relatively many animals in the next generation that are also very well adapted (provided that the offspring inherit this from their parents ). Conversely, the least adapted animals will have fewer offspring.
If you repeat this process over many generations, you can see changes in temperature adaptations (which may not be very noticeable) but possibly even other species can arise.
It is therefore impossible to speak of biological evolution within the life of one animal, it is a process that takes place generation after generation. So your example is not about evolution.

Does this mean that an animal cannot adapt at all during its life? No. To begin with, animals not only have a certain temperature at which they feel most comfortable, but a whole range in which they can also survive. Unsurprisingly, this range is larger in animals that live in highly variable environments and smaller in animals that live at a nearly constant temperature (such as cave animals). You guessed it, it’s because of evolution.
If that range isn’t enough, it may be possible to make animals gradually adapt to a low temperature, as you suggest. However, the extent to which this is possible will differ greatly from one species to another and even from one animal to another. In some animals it may not work at all.

What I said above applies especially to “cold-blooded” animals. The “warm-blooded” animals, so birds and mammals, to which we belong, have found a good trick to be able to function in many different temperatures: they have their own heating system that keeps their body at a good temperature (with us 37° C) and when it gets too hot, they cool down by sweating (like humans) or panting (like dogs).
This of course costs a lot of energy and “warm-blooded” animals cannot go weeks or months without food (this is quite normal for many “cold-blooded” animals!) but the advantage is: they are less dependent on the “outside temperature”! It is therefore no coincidence that you find birds and mammals everywhere, from pole to equator, and from the beach to the mountains, but no snakes or frogs.

Sorry for the long answer ;-).
A short answer to your question could be: sometimes, but then it is not evolution.
