Summary Introduction
To discuss: The ways in which adaptive features may have become modern maladaptations.
Introduction: Humans show a high degree of adaptive flexibility. Moreover, different populations exhibit a wide range of genetic adaptations, for example, climate, and developmental adaptations, for example, to altitude. The developmental adaptations permit for survival for a longer period across a wide range of environmental settings.

- One of the main characteristics that defines the hominin tribe are their bipedal tendencies. However, as you have noted in reading for this week's assignments, not all hominins had the same bipedal capabilities. Early hominins can be defined as being at various stages of transitioning into bipedalism while later forms are obligate bipeds. At the same time there are many other things that we can explore that relate to hominins. Often times there are new discoveries that are made and those discoveries make the news. For this discussion board, I would like you to share a news article that specifically deals with hominins. The news article can be up to 10 years old. Make sure you do the following for points. Note: Make sure that the news that you read only deals with one of the following genera - Sahelanthropus, Ardipithecus, Australopithecus. Give a brief summary of what you read. In one short paragraph tell the class what the news was about. Include the following points.

- Discuss the differences between the Turkana Boy and the Dmanisi fossils. Indicate the importance of those differences. - What major hominin fossil discoveries were made in 1984 near Lake Tukana in northern Kenya? State the implications for human evolution. - Explain how changes in the teeth of humans are related to the growth and development of humans and chimpanzees. How can you calculate the age of a fossil from the teeth?arrow_forwardWhat is the difference between a "derived" versus a “primitive" trait? Give an example of both, seen in Au. afarensis. Which of the paleoenvironment hypotheses have been used to describe early hominin diversity, and which have been used to describe bipedalism? Which anatomical features for bipedalism do we see in early hominins? Are these primarily obligate bipeds? Explain. Describe the dentition of gracile and robust australopithecines. What might these tell us about their relative diets? List the hominin species argued to be associated with stone tool technologies. Are you convinced of these associations? Why/why not?arrow_forwardOn average, Black Americans have shorter life expectancies than White Americans. Which of the following contributes to this difference? A. In recent years, alcohol and opioid abuse have had the biggest impact on life expectancies for Black Amerians relative to any other racial or ethnic groups. B. Black Americans are more likely to have regualr cancer screenings and so have a higher recorded incidence of cancer. C. The youngest generations of Black American are less health than older generations, so health amoung Black Americans has been getting worse over time. D. Black Americans ten to receive lower-quality care and spend less time with medical practitioners than White Americans do.arrow_forward
- Suppose Inverness was considering offering a special add-on to its standard Dental insurance. For an additional 1 dollar a month a family could be fully covered for professional teeth whitening, something that normally would cost five thousand dollars a treatment. The whitening procedure would erase any stains that build up over time as a result of drinking too much coffee. Would this benefit create an adverse selection and/or moral hazard problem? If so explain why, and how the benefit could be better designed to address these issues.arrow_forwardFossilized remains of prehistoric mastodons show anatomical similarities to modern-day elephants. These similarities provided the first evidence that mastodons were related to modern-day elephants. Which of the following is the BEST additional evidence that mastodons were related to elephants? O A. Mastodons ate a diet similar to that of modern-day elephants. O B. Mastodon fossils were found in the same area where modern-day elephants live. O C. Mastodons walked on four legs like modern-day elephants. O D Mastodon tissues contained proteins with similar amino acid sequences compared to modern-day elephants. e here to search lp BANG & C 40 % 8. 4 WE R SD F GH M X CV Barrow_forwardHomo erectus was likely the first hominin to successfully migrate to regions beyond Africa.

- We have discussed the role of meat consumption in hominin evolution as an important source of fuel for our larger and metabolically costly brains. Do you think this hypothesis for why we have such large brains has merit? Why or why not? Can you think of any alternative hypotheses to explain the trend toward larger brain size over the past 2.5 mya?arrow_forwardApart from the actual physical evolution of HOMININ, there has also been an evolution in the type and method of food intake of hominins from Ardipithecus to Australopithecus and Paranthropus (so together they are both Australopithecus), to Homo habilis to Homo erectus to Neanderthals and finally to Homo sapiens. Explain this by defining the difference using the groupings I mentioned.arrow_forwardAccording to "The Life and Death of a Neanderthal (Shanidar 1)”, What does it say about his community? A.There’s no way he could have survived these injuries on his own. Homo sapiens must have cared for him because they were the only species that had any medical knowledge. B.There’s no way he could have survived these injuries on his own. Other Neanderthals must have cared for him, brought him food, possibly amputated his arm so that he could live. C.Nandy survived with these injuries on his own because his entire community was killed and Nandy lived alone. D.Nandy survived with these injuries on his own because his community did not take care of each other.arrow_forward
