Human Evolution: Ideas And Opinions Related To Evolution

1249 words - 5 pages

Australopithecus afarensis who existed 3.5 million years ago and a 4.4 million year old skeleton of an Ardipithecus ramidus are the closest science has come to discovering the human lineage. Shattered Ancestry an article written by Katherine Harmon discusses the remains of two hominids found within Ethiopia. These skeletal remains have created a huge controversy within the topic of evolution questioning many assumptions that have been made referencing the human lineage. The skeleton of the Australopithecus afarensis was named Lucy and was discovered in 1974. The evidence of her walking upright on her two feet essentially guaranteed her a spot in the human lineage line. Lucy was a chimplike ape that was said to walk upright making scientists believe the human ancestry was simple. The complete skeleton found in Ethiopia of an Ardipithecus ramidus named Ardi completely changed all assumptions made from scientists about the complexity of the human lineage. These remains have encouraged researches that the human line is not the only lineage to have evolved but the chimpanzee line has undergone drastic changes as well. There are many traits that researchers have always directly linked to the human lineage however since these discoveries occurred researchers are reconsidering. The recent discoveries that have shattered what has always suggested what linked a species to the human lineage have changed the certainty of whether it is possible to confidently identify the human’s last common ancestor. Majority of scientist had forgotten that there would have been many hominid species living together at one time. New theories have been suggested since scientists revealed that the foot of a hominid found called the Burtele site was found just 48 kilometres

from where Lucy was found. These two species were active during the same time era and therefore would have coexisted. (Harmon, 2013) Scientists are slowly realizing that different species develop similar traits independently. (Scientific American is part of Nature Publishing Group) The ideology behind human evolution has never stopped changing; the more science is discovering the less likely the chances of correctly identifying the human evolution line becomes. This relates directly to anthropology as it is the study of humans in the past and the biological science behind the human lineage. Evolution is constantly being challenged and criticized as a scientific theory. It is a controversial ideology as evolution is a very slow moving process, it is extremely complex, and there is no scientific proof of it ever occurring.
An article called The Trend of Human Evolution written by Franz Weidenreich challenges the assumption that humans were created through a process of evolution. Weidenreich explains that what has made evolution so difficult for people to understand and for scientists to prove is that nobody has ever watched it occur. Sections of evolution are said to happen extraordinarily quickly...
