1Australopithecus afarensis which existed 3.5 million years ago and a 4.4 million year old skeleton of an Ardipithecus ramidus are science closest to the discovery of the human lineage. Shattered Ancestry, an article written by Katherine Harmon discusses the remains of two hominids found in Ethiopia. These skeletal remains have created a huge controversy on the topic of evolution, calling into question many hypotheses referring to the human lineage. The skeleton of Australopithecus afarensis was named Lucy and was discovered in 1974. The evidence that she walked upright on two feet essentially guaranteed her a place in the human lineage. Lucy was a chimpanzee-like ape who walked upright, leading scientists to believe that human ancestry was simple. The complete skeleton discovered in Ethiopia of an Ardipithecus ramidus named Ardi has completely changed all assumptions made by scientists about the complexity of the human lineage. These remains have encouraged research that the human lineage is not the only lineage to have evolved, but the chimpanzee lineage has also undergone drastic changes. There are many traits that researchers have always linked directly to the human lineage, but since these discoveries, researchers are reconsidering their thinking. Recent discoveries that have shattered what had always suggested what linked a species to the human lineage have changed the certainty about whether the last common human ancestor can be positively identified. Most scientists had forgotten that there would have been many species of hominids living together at the same time. New theories have been suggested since scientists revealed that a hominid's foot found at the Burtele site was found right in the middle of the paper. Scientists explain that this is happening based on previous research and what humans have done. what I know is that it is too complex for average human knowledge to understand. Humans generally choose to believe what there is evidence for and in the case of evolution, there is none. In reality, the idea of ​​evolution is too complex and the general public finds it improbable. icr.org/home/resources/resources_tracts_scientificcaseagainstevolution/ http://www.theguardian.com/science/brain-flapping/2013/jul/10/human-evolution-next-stageshttp://www.jstor.org/discover/ 10.2307/2405324?uid=3739448&uid=2134&uid=376074841&uid=2&uid=70&uid=3737720&uid=3&uid=376074831&uid=60&purchase-type=article&accessType=none&sid=2110290617 3011&showMyJstorPss=false&seq=2&showAccess=false
