Summary Introduction
To identify: The geographic source of men carrying the given Y chromosomes is African, Eurasian, Amerindian, and first migrants out of Africa.
Concept introduction: Hominins are the group of all extinct human-like species and showed the unique characteristic of bipedalism. The Homo species’ fossils were discovered in several parts of the world based on which the human migration pattern was studied.

On an island with no large predators, some ducks are born with a mutation that gives them stubby little wings. These ducks can’t fly, but there’s really no need to fly since there are no predators. In fact, they have an advantage because they don’t have to eat as much to support those big wings like the other ducks. Over time, the flightless ducks reproduce better than the regular ducks, and eventually all the regular ducks die out. What characteristic of life is being demonstrated here?

Natural Selection: Imagine that a population of Cnidarians with life cycles that alternated between sexual and asexual reproductive phases evolved from ancestors whose life cycles lacked asexual phases. Explain how this may have occured via natural selection. In your answer be sure to address all of the key points discussed in class as being necessary to describe evolution by natural selection

- Example 3The Basque people, who have a distinct language, live on the coastal border of France and Spain. The 700,000 modern Basques had long been thought to descend from hunter-gatherers who lived in the area about 7,500 years ago, before the first farmers arrived. DNA told a different story. Researchers compared the genome sequences of bones from eight Basque farmers who had lived in a cave in northern Spain from 5,500 to 3,500 years ago to genomes from other skeletons representing severalEuropean hunter-gatherers and early farming groups, as well as to modern Europeans. While the ancient farmers had genomes representing many groups, including those of hunter-gatherers, the Basques indeed have a unique genome – but one that descends from the earliest farmers, not from hunter-gatherers. Apparently, their uniqueness today is due to their self-imposed isolation as the rest of Europe interbred. Source: Lewis, Ricki. Human Genetics Concepts and Applications (2018). Twelfth edition.…arrow_forwardEVOLUTION LINK Darwins theory of evolution by natural selection is based on four observations about the natural world. One of them is that each individual has a combination of traits that makes it uniquely different. Darwin recognized that much of this variation among individuals must be inherited, but he did not know about Mendels mechanism of inheritance. Based on what you have learned in this chapter, briefly explain the variation among individuals that Darwin observed.arrow_forwardOne of the key ingredients of evolution by natural selection is variation. Within a population, evolution by natural selection will occur if there is a selective advantage of one variation over another. What are the sources of variation in living populations? Select all that apply. a random mutations to DNA when DNA replicates in reproductive cells b environmental factors that may mutate DNA in gametes c mutations in somatic cells d crossing over during meiosisarrow_forward
- Imagine your anthropology professor studies a primate that eats insects. The primate's favorite food is a type of ant. She asks if you are interested in helping her analyze the data. You, of course, say yes! Your professor tells you more about the ants, the primates, and the habitat. Ant color is determined by one gene. There are two alleles for this color gene: the brown allele and the green allele. The primates eat the ants year-round, but your professor knows that the way they eat the ants differs between the rainy season and the dry season. During the rainy season, when there are green leaves on the trees, the primates eat the ants off the green leaves. During the dry season, when the trees lose their leaves, the primates eat the ants off the brown tree branches. Your professor has collected data to investigate if the primate acts as a selective pressure on the ant population, possibly changing the allele frequencies over time.arrow_forwardGive a Darwinian explanation of how cheetahs evolved to become faster. Your explanation is how natural selection works using Cheetahs as an example. Be sure to include and explain the ideas of differential reproductive success and descent with modification.
