As spider monkeys swing and move from trees to trees, they grip the branch with their hands.

The smallest known is the talapoin with the body length of 13 to This grade contains gibbons and siamangs, orangutans, gorillas, chimpanzees, bonobos and humans.
They have relatively long forelimbs and short truck which is a result from adaption for knuckle-walking.
Adult males can weigh up to pounds and females, usually half of the size of silverback, weigh around to pounds. This is now a part of the middle ear in all vertebrates, including humans.
They have the same basic structure but may appear somewhat different depending on the degree of modification produced by evolution.
The tail, which looks like thick fur is variety of colors. Even though bats and birds forelimbs are suited for flying, they are quite different. Whales have undergone many evolutionary changes over millions of years.
They are slow and careful which contributes to the challenges of their predators to find lorises. The evolution of human mating: Their feet have particularly elongated tarsal bones ankle regionwhich the name of the animal is derived from.
Whales, otters and penguins have forelimbs which are modified to allow them to swim efficiently. Thus, the presence of homologous organs in different animals provides evidence for evolution by telling us that they are derived from the same ancestor who had the 'basic design' of the organ on which all the homologous organs are based.
Male can weigh up to pounds and grow up to 5. This was discovered by finding remains of some fossils. Whales, otters and penguins have forelimbs which are modified to allow them to swim efficiently.
They have non-prehensile tails but some species like colobus monkeys use their long tails to balance.
The forelimbs of a human mana lizard, a frog, a bird and a bat have the same basic design of bones. When the land mammals evolved into water mammals, the inner ears of whales evolved to help them be flexible swimmers and prevent them from becoming dizzy when they swam.
But they sometimes walk bipedally for short distances for carrying food or defending themselves. They have a thin tail that is about 7. Therefore vertebrate forelimbs are homologous structures.
But they can also leap up to 26 ft and walk bipedally with arms raised for balance. Prehistoric ear bones could lead to evolutionary answers. They have long, curved and slender digits on hands and feet with shorter thumb which help them to grab onto branches easily when they brachiate.
Comparative anatomy is the study of the differences and similarities in structure between different organisms. The study suggests the canals are the ones which developed into true ears.
