In studying recent fossils of the genus Homo, such as Cro-Magnon,biologists have determined that modern humans have not undergonemuch biological evolution in the past 50,000 years. Rather, culturalanthropologists argue that cultural evolution has been far moreimportant than biological evolution in the recent history of modernhumans. What do they mean by this? Support your argument withsome examples.

There is no concrete evidence of which early hominin was our direct ancestor, as fossils do not contain genetics. Overall, the Australopithecines are the "missing link" bridging our ape to human transition. Each species, and there are a few, includes a combination of traits considered more ape-like or more human-like. How does this affect society feelings/views/ideas about early human evolution and what the "missing link" should or should not be.
There are two hypotheses to explain the pattern of Human Evolution: 1) Progressive Evolution of a Single Lineage ; 2) Evolutionary Radiation Which of these hypotheses are supported by evidence, and briefly explain why? Please explain in details
Some genetic studies suggest that the most recent common ancestor of Homo sapiens that lived outside of Africa spread from Africa about 50,000 years ago. Compare this date to the dates of the fossil record. Can both the genetic results and the dates ascribed to the fossils be correct? Explain and Justify.
Adaptations are physical or behavioral traits that help an organism survive in its environment. What are some of the adaptations in the evolution of hominins that allowed for the evolution of the genus Homo to evolve (eventually) into modern humans (Homo sapiens)? (Note: you don’t have to explain why these adaptations allowed the genus to evolve, just list some of the adaptations.)
The Evolutionary History and Spread of Our Species (Homo sapiens) a. Briefly describe the two major theories discussed in this chapter about the origin of modern humans. b. Which of these two theories would predict a closer relationship for the various modern human populations? c. Which of the two theories is best supported by the genetic evidence?
Paleoanthropologists generally agree that Homo erectus belongs in our genus and represents a significant shift towards adaptations important to our own species. However, there is much variation among specimens that are grouped into H. erectus. Your instructor will let you know which of these fossil representatives to use for the exercise today.Based on your measurements and comparisons in the table above, what are major differences among Au. africanus, H. habilis, and H. erectus? Do you think H. habilis is more like Australopithecus or Homo? How do these three species reflect the major environmental pressures of the time periods in which they lived, respectively? List three features that are changing in the genus Homo due to these selective pressures. List three features found in H. erectus that are derived, compared to Au. africanus.
What can we say about Homo sapiens? Select one: O a. Originated in Africa, shared a common ancestor with Neanderthals, Denisovans, and most likely descendants from a group related to Homo heildenbergensis O b. Migrated out of Africa, most likely 2 million years ago, hybridized with Homo floresiensis and differentiated from other Homo as the sole species to evolved language. O c. Migrated from Ethiopia 200,000 years ago, hybridized with Denisovans and Neanderthals to later replace them O d. Is the result of hybridization between Neanderthals and Denisovans, only lineage to show bipedalism and posses the largest brain capacity of all Homo O e. A and C are correct
Which statement is a tenet of the out of Africa hypothesis for the origin of modern humans? O O O O Modern humans evolved in Africa and then migrated throughout the world, replacing earlier human populations. O Modern humans evolved in Eurasia and migrated to Africa, driving resident populations of early humans out of Africa and resulting in their extinction. Homo erectus populations migrated out of Africa and interbred with Homo neanderthalensis populations in Eurasia to give rise to modern humans. O Numerous Homo erectus populations that scattered throughout the world evolved simultaneously to give rise to modern humans.

We have studied how the six major primate groups evolved, with the most recent group being the hominins.The hominins branched off from main ape group around 7 million years ago.According to our lessons explain your reasoning as to whether there is a missing link,or one single specimen that embodies both ape and hominin traits, that serves as a transition between what is clearly ape and what is clearly hominin?What have you found most interesting about the beginning of hominin evolution and why?
Neanderthals are recognizably human but have distinctive facial features and a stocky build that were evolutionary adaptations to cold, dry environments. They shared Europe for 10,000 years with Homo sapiens. Today they no longer exist. Beyond these facts the fate of Neanderthals has generated much debate. Why did Neanderthalsbecome extinct? State at least two major factors toexplain their fate.
