Hominid

What evidence did you find that indicates relatedness between early and modern hominids? Our evidence of the relatedness between early and modern hominids is the we have the same head features such as molars, canines, protrusion of the lower face, and the same orientation of where the spine connects with the skull. The size of the these features range in size, for example the A. africanus lower jew had 2 molars that were 2 cm, each one about 1 cm in size. Our Homo sapien skull had 3 molars (meaning

that bipedalism starts to appear. This hypothesis is hard to prove, however, logically speaking, carrying highly energy-rich food such as nuts or fruits is beneficial to the group and community. A study conducted in West Africa suggests that early hominids walk upright to carry resources away from other competitors. Researchers provide piles of oil palm and nuts to 11 chimpanzees, who prefer the nuts. According to the research, the chimps are four times more likely to walk upright with two legs, so

chimpanzees. This transition to bipedalism was facilitated by structural changes comprised of an angled thigh bone, a more sturdy and broad pelvis, a wider patella, an S-shaped spine, and long femurs. The compilation of all of these adaptations allowed hominids to not only support their entire body weight while standing upright, but efficiently take long strides, therefore allowing them to travel greater distances. Though much is known about the implications for the transition to bipedality, the

social lives have evolved from the very early times of the hominids. Cultural behavior grew extensively from the era of the homo habilis and the homo rudolfensis. Hominids recognized the importance of adaptation and organization as a means of survival. The skills and tools developed did not depend on intelligence but rather improved social organization. Survival required a coordinated approach where information could be shared amongst hominids with a similar cultural behavior. They required a means

Bipedalism, a locomotion that consist of the two lower limbs to move. This can be found in many animals, but it is considered more “optional” than “mandatory” as a way to transport. Some use it as a defense mechanism. In humans, it is one of the special characteristics that is used to differentiate the human species from the rest of the Hominidae family. Only humans have “mandatory” bipedalism. Other characteristics include massive brain size and the ability to make and use tools (Lovejoy,1988).

supposedly explains human-alien abduction cases, possibly collecting more DNA to make the next hominid species. This proposition was extremely weak due to the lack of solid evidence. Using the concept of Occam’s Razor in order to believe that Aliens created Humans, one must make plenty of assumptions that they mixed ape DNA, and that this is why we have “alien” abductions involving humans, also that they made past hominid species and are making more in the future after us. Evolution explains this in one easy

A significantly enlarged brain size is one of the main features distinguishing modern humans from other hominids. Humans are unrivalled in both their cognitive and linguistic capabilities, and since an expanded brain appears to be correlated with intelligence (Darwin, 1871), it is not surprising that the evolution of modern humans was believed to be the result of increased brain size and complexity. However, the fossil evidence has revealed that an increased brain size evolved only after the evolution

evolutionary phenomenon was happening in Africa. Early hominids, man’s ancestors, were beginning a giant leap in their evolution. These hominids were moving out of the forest and beginning to walk upright, out on the open plains (Fagan, 98). This change from quadrupedalism was the most significant adaptation that ever happened to these early hominids. It caused many adaptations that make man what he is today. This process occurred in early hominids for many different reasons, each reason helping to

Chimpanzees, also known as Pan Troglodytes, are an African species of great ape which have a stronger degree of relation to us than to gorillas (National Geographic, n.d.; Gebo, 2014). They move both on land and in trees, mainly eating and resting above ground. An opposable thumb and four fingers provide the ability to cling to trees, and the strength for this comes from a variety of muscles such as the deltoid. The can move swiftly on land due to no tail and a plump body. Quadrupedal locomotion

afarensis was an early bipedal species of hominin that possessed several features similar to both apes and humans. The discovery was made while driving back to camp when Donald spotted a right proximal ulna (forearm) and identified it to belong to a hominid. Within minutes of excavation, he discovered the skull, several ribs, a femur, pelvis, lower jaw and several other fragmented bones. Roughly 40% of the total skeleton was recovered in total. The specimen was named lucy after the popular song by the
