To the ongoing question as to how humans evolved has still been a debate over several decades. Homo sapiens is a scientific name given to humans. Homo sapiens are classified under the kingdom-Animalia, phylum-chordata, class-mammalia, order-primates, family-Hominidae, genus-Homo and species-sapiens. According to Linnaeus Carlos, scientific way of classifying living organisms (Relethford, 2010). According to Relethford, Hominin is a tribe that comprises of humans and their closest ancestor. Hominin family has shown some resemblances with the evidences collected from fossil records as well as the evolutionary processes to the mordern humans. This article will try to describe the evolution of homonin tribe from the time period of Homo habilis…show more content…
Although they lacked a chin, they possessed slight brow ridges which show a transition towards the Homo sapiens. Archaic sapiens showed similar brain size seen in humans about 1350 C.C. with no sagittal kneel (Relethford, 2010). The stone tools found associated with Homo heidelbergensis were manufactured in a sophisticated way using Levallois technique. This technique produced sharp and efficient tools. This showed how skilled archaic humans were similar to modern living humans (Relethford, 2010).
Not only did Archaic sapiens have close resemblances to humans with some primitive characters, but also Neanderthals species who lived in Europe between 130,000- 28,000 years (McKee et al. 2005). They lacked a chin, large teeth, large nasal region, curved thigh bones due to poor health, occupational bun. It was suggested that the frontal large teeth compared to the back was due to using them as tools (Relethford, 2010). The large nasal regions were suggested to be an adaptation to the cold weather and were not seen in other Neanderthals in different geographical regions (Relethford, 2010). Surprisingly, they possessed larger brains about 1500 C.C. compared to humans. This still brings a debate whether to classify the species in a same or different group for ancestors of living Homo sapiens (Ruff et al. 1997). The stone tools found associated with Neanderthals where similar to the ones
