Name an animal that can walk with four and two legs for a long period of time.?

Answer 1

Living animals that are at least partially bipedal, and able to rear up on hind legs for a short period of time include bears and raccoons - but they can't keep it up for long.

The great apes, such as chimps, gorillas and orangutans are pretty much the best at it of living critters. Other apes, like gibbons don't really walk on all fours at all - their arms are too long, and we don't walk on all fours because our legs are too long.

Some of the prosimian primates, like bushbabys (galagos) are pretty good at moving on two or four legs.

Jumping mice (Zapodidae) usually move on four legs, but can hop on two for high speed sprints. Other families of ricochetal rodents (kangaroo mice, jerboas) move about on two, but often drop to four legs for foraging and slower movement.

There's some lizards that take to bipedalism for high speed movement (frilled lizards, basilisks). They can't stand on their two legs for long though - only while they're moving.

There are some primitive kangaroo relatives - potaroos, bush wallabies, etc. that are usually quadrupedal, but go bipedal for speed. The larger macropodes (like the kangaroos and wallabies) will sometimes drop to four legs for low speed walking.

The most definite bipedal/quadrupedal switchers were probably some of the extinct dinosaur lineages though. The ancestral dinosaur condition was bipedal, and most lineages retained this pattern (i.e. raptors, T. rex). Even the quadrupedal dinosaurs still had most of the their weight distributed over their hips, with the hind legs supporting most of their weight. Critters like the giant sauropods, stegosaurs and even ceratopsians would have had a much easier time rearing back on two legs than a cow or rhino would.

But the best were probably the hadrosaurs. Also known as 'duck-billed dinosaurs', these critters were probably mostly quadrupedal. However, they would have been able to rise up on their hind legs quite easily - in fact, many reconstructions have them in a bipedal pose based on what they originally thought of the skeletal remains.

Answer 2

A small question: clay, dust, water, dirt? Where do these fit when man was being created? To continue....... A little bit of shaping of an anthropomorphic form of Allah's choosing then breathing into man of his own soul with a decreed life span, wealth to be earned during that period, good and bad events to befall the individual in question and there you have it. Allah's creation of Man ! Peace be upon you.
