Zoology Introduction

Zoology is the study of animals it is one of the braodest felds in all of science because of the immense variety of animals and the complexity of the processes occurring within animals. Entomology is the study of insectects, Herpetology is the study of amphibians and reptiles and ornithology is the study of birds.All animals share a common evolutionary past. Organic evolution is the change in the genetic makeup of populations of organisms over time. It is the source of animal diversity and it explains family relationships within animals groups.


Fun Facts!There are over 20,000 species of bony fishes and over 300,000 species of beetles!!

Ecology is the study of the relationships between organisms and their environment. Throughout our history humans have depended on animals, and that dependence too often has lead to exploitation. Humans have a tendency to be wasteful and non-observant of the environment around them. As a result we mess up the delicate balance of he ecosystems. This can be seen in deforestation and the many endangered species on our planet

Global overpopulation is at the root of all other environmental problems. Most of the growth is in less developed coutnries where 5 billion out of 6.3 billion humans now live. It is estimated that the world population will reach 10.4 billion by the year 2100. Human overpopluation stresses world resources. This createss an increase in the use of fossil fuels which in turn causes issues like global warming, deforestation, and loss of habitat. The effects of all of this is extinction and endangering of species.
