Document Summary

What he found about geographic distribution of species: Two main points of the theory of evolution. Natural selection a population of organisms changes over generations if they are inheriting certain genes that allow them to leave more offspring (higher fitness) All life is part of a ladder of life". Rocks, plants, lower animals, higher animals, humans, god. Old testament: all species are created individually and are non-evolving. In the 1700s, natural theology study nature to classify things on the ladder of life. Wanted to classify everything made binomial nomenclature. Sought to discover order in the diversity of life. Did not imply relationships between species, although other people that came after him would do so using his information. New layers of rock cover old ones and are compressed into strata. Some species disappear from one strata to the next. Found that species from tropical regions of south america were more related to species from temperate south america than tropical africa.

Biological evolution is the process whereby earthâs life changes over time through changes in the genes of populations of organisms in succeeding generations. Species have evolved from earlier, ancestral species through natural selection. Discuss this process in detail. Why is this beneficial for species? Why do you think there is controversy about human evolution?

Describe the theory of natural selection Which of thefollowing BEST describes the theory of natural selection? CHOOSEONE

	1 The genetic make-up of apopulation gradually changes from one generation to the next.
	2 Living organisms change overtime.
	3 Each species produces many moreoffspring than can survive long enough to reproduce. The offspringthat do survive contain genes that are inherited from theparents.
	4 There is variation among themembers of a species. Some of this variation is geneticallydetermined and so can be passed on to future generations.
	5 Some individuals have genes thatincrease their chances for survival and reproduction. Theseindividuals are more likely to reproduce and pass on their genes,causing their genes to become more common in the nextgeneration.
	6 There is a struggle for existenceamong the members of a population.

1. James Hutton was the first to propose that geological change occurred gradually by the accumulation of small changes from processes that are occurring today, but who was the first to popularize this idea with additional geological evidence and to inspire Darwin to consider that the earth is millions of years old instead of only thousands of years old?

Charles Lyell

Charles Darwin

Jean-Baptiste Lamarck

Aristotle

Aristotle was perhaps the first person to classify organisms, but who was the first to develop a systematic approach to classifying organism in the 1700s that is still partly used today?

Galen

Carl Linnaeus

Stephen J. Gould
