There has been much debate over where Homo heidelbergensis and Homo  neanderthalensis fit into the evolution of humans. Some say that there is no way  that Homo heidelbergensis or Homo neanderthalensis contributed anything to the  evolution of modern humans, others say that they did. Either way that you look at  it, learning more about Homo heidelbergensis and neanderthalensis is important to  understanding the origins of modern humans. Both of these Homo species have  primitive and modern humanlike traits to them. To decide whether or not Homo  heidelbergensis, Homo neanderthalensis, or both evolved into humans is a difficult  task to tackle. Since both have characteristics that point away from evolving into  humans, and some pointing towards evolving into humans. Homo neanderthalensis lived about 300,000 years ago, in Europe and the  Middle East. There were many different types of Homo neanderthalensis usually  separated into three different groups: Early Neanderthals, Upper Paleolithic  Neanderthals, and the Late Surviving Neanderthals. But the average brain size was  about 1400 cc, some scientist think that this could possibly be because since Homo  neanderthalensis was able ward of any other predators that would compete with  them for larger prey. So in turn, Homo neanderthalensis was able to retain more  nutrients, therefore developing the brain larger, all while increasing the body size.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
