Chapter 23, Problem 2TC
In studying recent fossils of the genus Homo, such as Cro-Magnon, biologists have determined that modern humans have not undergone much biological evolution in the past 50,000 years. Rather, cultural anthropologists argue that cultural evolution has been far more important than biological evolution in the recent history of modern humans. What do they mean by this? Support your argument with some examples.

One compelling piece of evidence for human evolution is the fossil record, particularly the
discovery of transitional fossils like Australopithecus afarensis. Lucy, discovered in 1974,
provides an essential link between us humans today and our ape - like ancestors. Her head
skeleton, especially the pelvis and leg bones, indicates that she walked upright, a key trait
distinguishing early hominins from other primates. This evidence is compelling because it
directly shows us physical adaptations in ancient species from millions of years ago that align
with the evolutionary theory of bipedalism. Supporting this theory the gradual changes
observed in the fossil record, from ape- like traits to more human-like features, offer concrete,
sequentially proof of how humans have evolved over the years.
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.)
In many ways, modern human lifestyles are at odds with our bipedal locomotion. At no point in history have humans been as inactive as today (especially in developing nations), which has led to a number of physical ailments, such as obesity, loss of mobility, and low back pain. What are some other impacts of evolution on our species? What are some ways we can alleviate these problems? You should include any recommended study tips, review videos, or other materials.

- 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.arrow_forwardPrimatology is part of anthropology because: Group of answer choices A: They can help us understand behaviors of hominins, which are ancestral to humans B: All of these answers are true C: There was nowhere else to put them D: They represent what we used to be before we evolved E: They are our closest living relativesarrow_forwardPaleoanthropologists 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.arrow_forward
- Some human traits may have arisen by sexual selection. Over thousands of years, women attracted to charming, witty men perhaps prompted the development of human intellect beyond what was necessary for mere survival. Men attracted to women with juvenile features may have shifted the species as a whole to be less hairy and softer featured than any of our simian relatives. Can you think of a way to test this hypothesis?arrow_forwardThere 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 detailsarrow_forwardHumans are grouped in the order of Primate because primates are mammals who have: O long legs, upright walking, hairless faces. five toes, no tail, short necks. large brains, opposable thumbs, long parental investment. speech, writing, technology. QUESTION 4 Family hominidae, to which human beings belong, includes: gorillas chimps bonobos all of the above.

- Some people think that many of our uniquely human traits arose by sexual selection. Over thousands of years, women attracted to charming, witty men perhaps prompted the development of human intellect beyond what was necessary for mere survival. Men attracted to women with juvenile features may have shifted the species as a whole to be less hairy and softer featured than any of our simian relatives. Can you think of a way to test these hypotheses?arrow_forwardWe 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?arrow_forwardRadiometric dating and the cranial capacity measurements are back from the paleolab for the specimen you discovered at the site you were excavating in South Africa. Lab results indicate that the cranial capacity is 520 cubic centimeters and it dates to about 1.5 million years ago. After having identified the cranial traits present, you can now take this new information and provide, at least, the genus to which you think it may belong. Based on this information, choose from the options below, the category to which you think it most likely belongs. -Pre-australopith -Premodern Human -Gracile Australopithecine -Early Genus Homo -Robust Australopithecine -Late Genus Homoarrow_forward

Of all birds, we have the most complete genetic data compiled for chickens. Of all chordates, birds (like chickens) are the most like dinosaurs. This will help to prove the theory of punctuated equilibrium.arrow_forwardcreate a phylogeny of human evolution. It should include all known hominids beginning with the earliest and ending with modern Homo sapiens. In your version of a future, humans will create a phylogeny of human evolution. It should include all known hominids beginning with the earliest and ending with modern Homo sapiens and your version of a future human. The requirement is to put the genus and species name of the hominid, beginning with the earliest one, which is Sehelanthropus tchadensis, in the phylogeny along with its dating age.arrow_forward
