Hominoids belong to the Hominoidea superfamily which is broadly classified into Hylobatidae and Hominidae families. The primates of Hylobatidae family are known as Gibbons. They are also known as the lesser apes are completely arboreal and confined to the trees…
Another classification involves two tribes, Panini and Homini. Both Pan and Gorilla genera are divisions in the Panini tribe, while Homini tribe includes Homo sapiens. Homo sapiens, better known as human beings belong to the Hominidae family and the Homo genus. Hylobates, Pongo pygmaecus, Pan paniscus, Pan troglodytes, Gorilla gorilla and Homo sapiens are the six different species of Homonoids.
Chimpanzees belong to the Pan genus. They spend a considerable amount of time on the ground and inhabit in large complex social groupings. They are specially adapted for knuckle walking. They also indulge in hunting as a group, sharing of food and tool making. They resemble our ancestors in anatomy as well as social behavior and are considered to be our closest living cousins. Orangutans belong to the Pongo genus. They are generalized climbers and are most isolated among the primates. Gorillas are the largest among primates. The male gorilla is larger and stronger than its female counterpart. The male gorilla has exclusive relationships with a group of females and keeps away male rivals from this group.
The Old World species exhibit sexual dimorphism as a result of polygynous mating system. Hence, the males are bigger and stronger than the females to attract and sustain the pressure of defending multiple mates. ...

The use of bipedality is one of the alternatives which have evolved through time among homo sapiens. This is directly attributed to not only needs for maneuvering and basic functions. Many theories also show that bipedality is related directly to the climate change and the stress which this caused on the human body.
Instead it reinforced the theory that says, modern apes are not at all primitive but they are as evolved as hominids “though within extant ape lineages” (Lovejoy et al., 2009, p.74). Ardipithecus ramidus with its features matching with hominids also gave rise to the conclusion that humans and Chimpanzees though might have had a common ancestor, soon after it’s progenies split into hominids and Chimpanzees, happened the decisive progress into the emergence of the genus, Homo, including the shortening of the canine teeth etc.
Though the fossil record of hominids is currently fragmented and incomplete, there is enough material present to provide a healthy sketch of the evolutionary history of homo sapiens. Inasmuch as the Australopithecines were "bipedal primate mammals," they can be classified as ancient hominids (Merriam Webster).
Recent Studies, according to the author have also depicted very different behavioural and biological patterns between the two species .The article addresses the issue of how these two species live as neighbours and how they behave next to each other being different members of the primate group.
The entirety of these differences is referred to as sexual dimorphism. Though comparatively minor in human beings, sexual dimorphism is relatively huge in some of humans’ closest existing relatives, orangutans and gorillas
They became extinct; it is not in doubt their close semblance to the early human ancestors. Experts in Hominid research refer to them as man-apes and also ape-man this is because they have features of the two groups,
But the fossil fuel excavation revealed that homosapiens have existed on planet about 1.8 million years ago. Since this fossil was founded in Northern Kenya the single species hypothesis was abandoned. Then it was estimated that many forms of species have co
Their existence was as a result of change in climatic conditions. This is because the period primates came into existence was also marked by changing environmental condition of pro-longed cold and dry period. These
The researchers were to base their re-examination on assemblage of manual elements sampled from Hadar, Ethiopia.
According to Rolian and Gordon (2013), the foundation for the conclusions was assemblage of A.L.
