Over the past hundred years, more and more fossils have been added to the world's fossil collection, fossils from all over the world. New theories have been created and old theories have almost been proven about the evolution of man. For example, we have evidence that different human species have existed with certain types of DNA sequences and instincts, some that we may no longer have, or others that other species did not have. at the time. Although much debated, one of the most widely accepted theories is that Homo sapiens interbred with the slightly more primitive human species, Neanderthals. It all started when the first Neanderthal fossil to gain much attention was discovered. found in 1856 in Düsseldorf, Germany, because it is the whole being rather than a few scattered bones (Walter, 102). Shortly after, another skull was discovered in Maba, China, which had the same similarities to Neanderthals. However, little archaeological work has been carried out in the Far East. Aiello, an archaeologist, says: “[There is] no doubt that Neanderthals could have migrated further east – to Mongolia or China… Nothing could have stopped them. » Neanderthals took advantage of a warm period 125,000 years ago to migrate. They eventually reached Siberia. During this warm period 125,000 years ago, the size of the Caspian Sea was significantly reduced (Than, 1). Remains of cave drawings of Neolithic people and human figures have been discovered and date back approximately 41,000 years (Hammer, 66). Chinese and Malay Homo Sapiens have characteristics very similar to those of Neanderthals. Skull analysis of Neanderthals and Homo sapiens is generally considered more accurate if the entire skull is examined, rather than some... middle of paper... in a precise form” (IBT, 1). To understand and prove this stuff, regions of the genome are compared to entire genomes. Before we can judge the pattern of human origins, we must be able to understand the coding of genes for human traits and so on. Paabo's team discovered an mtDNA sequence from a finger bone they found about 40,000 years ago, in carbon form. Dating is one of the most commonly used methods to determine the age of a fossil. (Hammer, 70). Furthermore, Neanderthal mtDNA differs greatly from modern human mtDNA. For example, microcephalin is a gene that determines brain size during the organism's development. The size of the modern human brain is significantly smaller than that of Neanderthals, as are their brain cavities. TAS2R38 is the gene that controls taste. For Neanderthals, having a bitter taste 'system' could have prevented them from accidentally poisoning themselves.
