Please help me solve these multi questions, as soon as possible I got stuck on it. Thanks so much for your help!

among their technological accomplishments, about 300,000 years ago, later premodern humans in Africa and Europe invented the prepared-core method for striking flakes from stone cores. O True O False Question 49 1 pts One striking feature of Neanderthals is brain size, which in these hominins actually was larger than that of H. sapiens today. O True O False Question 50 1 pts Neanderthal remains have been recovered from Europe, Asia, Africa, and Australia. O True O False Question 51 5 pts Neanderthals have often been portrayed as nasty, brutish and fundamentally different from Homo sapiens. However, recent findings presented in class and described in the textbook suggests a different scenario and relationship between the two hominins. Address the genetic evidence for interbreeding between Neanderthals and Homo sapiens. Where and when did contact occur between Neanderthals and humans? Which modern human populations have Neanderthal DNA? In contrast, which modern Homo sapiens do not have Neanderthal DNA?

How have the recent findings associated with the fossil "Ardi" (Le, Ardipithecus ramidus) challenged our understanding of the evolution of bipedalism? Did hominins quickly evolve from quadrupedal to obligate bipeds? What about the environment in which bipedalism evolved? How does this compare with previous models for the evolution of bipedalism?
