Homo neanderthalensis, Australopithecus afarensis, Homo habilis, and Homo erectus. According to fossil records and discoveries, how do these human species vary?
Step by step
Solved in 2 steps
- 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 Neanderthals become extinct? State at least four major factors to explain their fate.Neanderthals are recognizably human but have distinctive facial features and a stocky build that were evolutionary adaptations to cold, dry environments.

State at least two major factors toexplain their fate.Some scientists suggest that the Neanderthals and possibly Denisovans, never went extinct, but instead where assimilated into Homo Sapiens. What evidence would you look for to support this hypothesis?Describe the major evolutionary advancements that took place among the australapiths and the early Homo species (e.g. Homo habilis & Homo erectus). In other words, what did modern humans gain from the australeiths and the early Homo? (Include the evolution of bipedalism, diet/fallback foods, body structure, tools, etc.)
- In what order of descent did the species of Homo overtake one another? What was discovered in the caves at Atapuerca, in northern Spain and what does this say about archaic Homo sapiens (Homo heidelbergensis in this case)? What is “Excalibur” and what did it signify (Maybe)? In what ways did our ideas about Neanderthals change as the 20th century proceeds? What recent discovery in the Meuse Valley, Belgium, helped to refine our views of Neanderthals? What kind of research is going at the Max Planck Institute in Leipzig, Germany, regarding evolutionary studies? Why are children’s teeth so valuable to archaeologists? Why was hunting such a risky business for Neanderthals? Why did Neanderthals go extinct about 25,000 years ago? (Note, since this film was made our ideas about this have changed as you will see in next week's film.) What is “the bottleneck effect”?Do you think Woolly Mammoths should be brought back from extinction? How about Neanderthals? why, or why not, in each caseNeanderthals DNA and behaviors show uS the ways in which they adapted to their environment over Europe, the Near East and Western Asia. Decoding Neanderthals discusses why Neanderthals went extinct. Which do you think best explains their extinction, and why?
- You are searching for hominin fossils in Africa and discover a skull with a sagittal keel, an angular cranial vault, a brain size of 900 cc, and a bar-like supraorbital torus. Which hominin did you most likely find? Homo habilis Homo erectus Homo neanderthalensis O Homo floresiensis Homo nalediPaleoanthropologists 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.A paleontologist finds a hominid fossil skull in a stratum dated at 4.4 MYA in eastern Africa. The skull has a relatively small braincasea and similarly-shaped teeth. Which of the following hominid species would the skull most likely be a fossil of? Homo erectus Ardipithecus ramidus Australopithecus africanus Homo neanderthalensis
