Because they are able to control their body-temperature

Cis or trans? That's what matters.

It is an adaptation to enable them to survive ice ages. Nature likes to fill every niche, and if half the world is uninhabitable because it is too cold for poikilotherms to survive, that's an awful waste of the planets resources. Evolution was always all about filling every possible niche. Life seems to have this very powerful urge to proliferate, with every species breeding to capacity. Why is this so? What is it that made this drive? And it isn't only sentient objects that have it. It's a universal law.

That would almost make sense (well, not really) - except that mammals were around long before any significant ice age periods.

Believe adaptation is an expression of phneotypic plasticity - not novel genetic establishment. Darby's point is a good one.
