Summary Introduction

To review:

The processes that might contribute to the evolution of Batesian mimicry in two butterfly species and would the same processes affect both the mimic and the model similarity. Also, determine the process that contributes to the evolution of the mutualistic relationship between ants and acacia trees, and the way in which their action on the two mutualistic differ.

Introduction:

The microevolutionary processes include changes like gene flow, genetic drift, mutation, natural selection, and nonrandom mating. These phenomenons affect the relationships and interactions between the species and therefore help them to evolve. The genetic drift is drastic extinction of a species by any incident, while gene flow is a movement of a species from its native place onto another land.

Mutation refers to an occurrence of any random change into the genes of an individual. Natural selection is the selection of better species among the existing population and nonrandom mating is the mating between two organisms of the same population.

PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen.     How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans?   Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
Other than oil and alcohol, are there other liquids you could compare to water (that are liquid at room temperature)? How is water unique compared to these other liquids? What follow-up experiment would you like to do, and how would you relate it to your life?
