Question

Describe Dryopithecus, Ramapithecus, Australopithecus, Homo erectus and Homo sapiens giving brain size and function, skeletal structure, dietary preference, etc.

Answer 1

Hint: Dryopithecus, Ramapithecus, Australopithecus, homo erectus and homo sapiens are the evolutionary stages of the humans and all this genus are extinct in nature, where they features are different and have some relation with each other.

Complete answer:
Dryopithecus: This animal mainly looks like a monkey comparatively rather than modern apes.
> When it comes to their walking nature they mostly resemble chimpanzees.
> And the walking is said to be the knuckle walking.
> The food nature of this animals are soft leaves and fruits
> Their arms and limbs both are similar in size.
> The canines of these animals are large in size.
Ramapithecus: These animals are mainly semi erect in nature, they resemble the man like.
> The body is designed in such a way that it mainly present on the ground and on the trees
> It mainly feeds on fruits and seeds
> The canines are large and molars are heavily build
Australopithecus: The members of the species has face like proportions
> The brain is very small compared to the human brain
> When come to the arms they are long and strong a d fingers are curved in nature
> This animals are mainly herbivores in nature
> Canines and incisors are very small in size.
Homo erectus: This animals are mostly resembles the humans
> They are highly erect in their posture.
> This animals are considered as ancestors of the humans
> They are omnivores in nature.
Homeo sapiens: This animals have highly developed brain and resembles humans
> They have slender trunk and the body and limbs are long
> They have wide range of adaptive environment

Note: The above discussed species are the animals which are in the process of evolution of humans, their development slowly increases with evolution and brain development increases with homeo sapiens and dietary nature and skeletal structure all depend on the body building and tooth development.
