Mammals were around when the dinosaurs were, we/they wer ebasically rodents until 64 millions years ago when the dinoaurs died out. Anatomically modern humans have been around for 500,000 years. Modern humans probably (mostly brain evolution is my theory) is debatable, but at least 50,000 years.
But basically, we're talking about a very long time period. 64 million years and more.
NO it can not they are not like humans .Any way humans breath properly differently even though they are mammals
Rats do not lay eggs (: They are mammals.
yes
The description matches that of fleas, which are small, slender, black insects that are capable of jumping long distances. Fleas are common pests that feed on the blood of mammals, including humans and pets. It is important to take measures to control and eliminate flea infestations to prevent bites and potential health issues.
Humans will normally resurface approximately 2-3 days after drowning. This is because of the gas forming bacteria in their bowels. I would assume cattle would be about the same.
They dont hatch . . . Chimpanzees are mammals. They are born exactly the same way humans are.
It needs to be level 16 to evolve.

Because mammals include humans, the list is overwhelmingly large. However, lawn and garden tools are not often used directly to care for mammals.
Pretty easy. They don't.

It'll evolve at level 40. It may take awhile.
Mammals produce a low number of offspring. Take humans, cats or dogs for example xHope i helped ;P
It evolves by trade,not level. So, it's your choice when you to evolve it.
A couple battles.
All you need to do it is evolve it with a Fire Stone. No leveling up is required, but recommended.
Very long.
