A later experiment with kittens raised in the dark and then placed on the visual cliff showed that depth perception was not innate in all species as the kittens would walk on either side of the visual cliff. After six days of being in the light, the kittens would avoid the deep side of the visual cliff (Rodkey, 2015).
Insects roamed the land and would soon take to the skies; sharks swam the oceans as top predators, [83] and vegetation covered the land, with seed-bearing plants and forests soon to flourish. Four-limbed tetrapods gradually gain adaptations which will help them occupy a terrestrial life-habit. 360 Ma First crabs and ferns.

Evolutionary theory says all animals that are walking on land actually evolved from sea-dwelling creatures at some point in the ancient past. To study this further, scientists from McGill ...
Cat species vary greatly in body and skull sizes, and weights: The largest cat species is the tiger (Panthera tigris), with a head-to-body length of up to 390 cm (150 in), a weight range of at least 65 to 325 kg (143 to 717 lb), and a skull length ranging from 316 to 413 mm (12.4 to 16.3 in).
A walking hamster. Animals show a vast range of gaits, the order that they place and lift their appendages in locomotion. Gaits can be grouped into categories according to their patterns of support sequence. For quadrupeds, there are three main categories: walking gaits, running gaits, and leaping gaits.
