Question

List and explain at least 4 of the 6 characteristics that make humans unique among primates and in the animal world. 2 points How are new species formed? What conditions are needed? What are three key observations that allowed Darwin to understand these processes? 2 points. Using a square, please show how you solve the problems below. 6 points: In a small population of people (a village, lets say) only a small percentage of people can NOT taste PTC and the rest could. All of the people in that population who could taste PTC decided to marry other individuals who could ALSO taste it. Feeling dejected, the non-tasters decided to move away and start another village on their own. Assume for this problem that all the men who were tasters happened to be homozygous dominant, and each of them married a woman taster who was heterozygous. Draw a square to show the outcomes of the crosses. What will be the genotype and phenotypes of the next generation in the 'taster village'? provide percentages for each. After those children grow up, and begin to have children of their own, what will happen to the percentages of tasters and non-tasters? What will be the genotype and phenotype percentages of the next generation? What evolutionary force is at work here? (Mutation, Gene Flow Genetic Drift (bottle neck or founder affect). Selection, or some combination?) What would be the genotypes and phenotypes possible for the new (non-taster) village if they also decided to only marry each other?

Explanation / Answer

1) Eventhough if there is many similarities with primates, there are some unique charecteristics which makes humans separated from primates and animals. It includes:

2) Separate groups of organisms belongs to the same species adapt in different ways and evolve varied charecteristics. As time goes, they will be entirely different , even they can no longer breed together. This is how a new species is formed.

Charls Darwin's theory of evolution states about two aspects namely natural selection and adaptation. He proposed five key observations, which include:
