Summary Introduction

Concept introduction: Animal phylogeny is a rapidly changing field. Biologists mostly depend on the fossils to compare the similarities of body plan and the pattern of development to determine the evolutionary relationships among various animal groups. Throughout evolutionary history, there are various changes seen in body plans. These changes in the body plan provide clues to animal relationships.

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.
