Neanderthal Ancestors of Modern Humans Essay Examples

Neanderthals interbred with human beings according to scientific studies. However, the Neanderthals became extinct. It is believed that the Neanderthals had the same brain like that of human being. However, Neanderthals were stronger as compared to human beings. Therefore they needed a lot of energy to survive. As competition with human beings for food increased, it is possible that the Neanderthals failed to get access to enough food as required by their bodies. This could have caused the death of the Neanderthals. Therefore even after interbreeding, the characteristics of the Neanderthals could not survive due to the fact that the environment could not support their body energy requirements. The Neanderthals also could only survive in very cold weather conditions. When the weather fluctuated, the Neanderthals could not adapt to the changes as human beings and this could have caused their death. Therefore, it is possible that after interbreeding with human beings, the creature that resulted died to the failure to adapt to changes in climate and this is why the current human beings have no traits of the Neanderthals.
