NOVA-BECOMING HUMAN 1. What features make Northeastern Ethiopia a prime location to find fossils? 2. How did ZeresenayAlemseged (the Ethoplian scientist) date the hominid fossil he found? How old was the fossil? 3. How did scientists estimate how old 'Salaam' was when it died? 4. Salaam walked upright. How do scientists conclude this? 5. In which bodily regions do Australopithecines like Salaam mostand leastresemble modern humans? 6. Much of Kenya is barren and dry now. What was the central African environment like before the time of Lucy&Salaam;, 3 million years ago? What happened as Salaam's time arrived? What is the evidence? hat are some of the hypotheses for the development of bipedalism (uprieht walking on two leyhExplanation / Answer
1) The Afar is known for the tribal people that locate the northeast region of Ethiopia's capital, Addis Ababa, also Africa's Great Rift Valley part that brodens south over Kenya as long as Mozambique. Now largely barren and empty, long ago, the Afar was a fertile place, there different lines of hominids -- no more ape but not yet fully human -- lived and arised their children also carry out the dispute of a changing environment, and there animals of all description create generation after generation of emerging descendants.
2) Scientist Zeresenay alemseged was searching for the fossilised ancestor, which is extremely rare. 1st thing spotted was little chick bone, but it was not the baby chimpanzee because as right side turned over he saw the more bones inside. After an comprehensive screening and excavation process, the team got the Selam's partial skeleton: the earliest as well as most complete human juvenile ancestor ever found. She is a member of the species Australopithecus afarensis (3-4mya), when she died she was 3 years old.
3) Zeresenay worked hardly to bail out her jolt skeleton, using dental tools then clear away the soil from her ribs and twisted spinal column basically grain by grain. The method took 6 years and is still ongoing. Selam’s skull was CT scanned that showed her sex as well as age at death to be driven
4) The post-cranial skeleton also produced various essential data lines concerning the locomotion (movement) and Australopithecus afarensis height. The femur, tibia, and foot shows that even at 3 years old, Selam (and thus the species she depicts) walked fully upright, whereas the shoulder bones are more likely to those of gorillas.
5) Slow growth of brain in Australopithecus afarensis, likely to the pattern of brain growth of modern humans, preferably than that of chimps; this may indicate a probable shift in behavioral in Selam’s species 3.5 million years ago also evolution of the slowed brain development pattern also maturity that we know of as “childhood” of human. Selam's brain size is approximately 330cm3 that is different from the chimps.
