Question

Cockroaches appeared on Earth more than 250 million years ago and are still thriving today. A giant deer appeared less than 1 million years ago and is extinct today. Why did one animal survive while the other did not?

Answer 1

adaptation

Answer 2

The cockroach is obviously more evolved than the giant deer.

It's all about "survival of the fittest."

If you trace the history of the giant deer back through the ages, you'll probably find that its distant ancestor was a mutated cockroach -- which went through a number of species changes before becoming a giant deer perhaps almost a quarter-billion years later.

The mutated cockroach was unfit to survive, but that didn't mean it ceased to exist in its own generation: it reproduced, and its unfit offspring reproduced, and their unfit offspring reproduced -- and further mutations happened along the way.

Presto! Giant deer -- which, being unfit for survival in its contemporary world, ultimately died-off.

Answer 3

Cockroaches are generalists. They eat anything, they live anywhere, and they are not particular about anything. Besides that, cockroaches are small and don't need a large habitat or much food.

A giant deer needs a bigger habitat and is more likely to need a specific diet. If people exist at the same time as a large mammal, the mammal is hunted for food.

Answer 4

Survival of the fittest! For whatever reason, the giant deer must have not been able to adapt to its environment (resources, predators). The cockroach has been able to adapted and fills its niche quite well.

Answer 5

Evolution is the answer and also there are many other factors. too but shorter the life span faster is the evolution . so insects live shorter than deers.

Answer 6

I like ecolink's answer. Nobody wanted to eat them, so man, the most prodigious predator on the planet, left them alone. No good recipes.
