Crunch the numbers on the animal kingdom’s sizes and shapes, and humans differ from each other far less than most species. Hendry and Queens University biologist Ann McKellar combed through the scientific literature on body size and length in more than 200 species, from insects to fish to birds and, of course, humans.

Do any animals never sleep?

The brain size of most of the animals is smaller than that of humans (1.2 kg). But there are still several animals that have a brain size larger than the humans.

Why do animals get bigger when they get bigger?

Perhaps being bigger allows animals to more easily escape predators — the larger a creature is, the more difficult for an attacker to overpower it. And being bigger allows a buffer if resources become scarce, because a larger body can store up more reserves.
