Evolution & Diversity of Life
1. Adaptation – characteristic that helps an organism survive and reproduce in its
environment
2. Species – group of organisms that can reproduce and produce fertile offspring
3. Natural selection – process by which organisms with favorable traits survive
and reproduce at a higher rate than organisms without favorable traits; survival
of the fittest
Do Species Change Over Time?
3 Theories:
A. Creationism – one Supreme being created the universe
B. Evolution – all life is related and descended from a common ancestor; change
over time
C. Intelligent Design – one Supreme being created the first cell and used evolution
as a tool to guide development of new species
Evidence of Evolution:
1. Fossils – solidified remains or traces of once living organisms
a. Paleontologist – scientist who studies fossils
b. Archaeologist – scientist who digs up ancient artifacts
2. Anatomy – study of the structures of living things
a. Vestigal structures – “leftovers”
3. Embryology – study of embryos as they develop
4. Biochemistry – study of chemical make-up of proteins
Grouping of Organisms
1. Classification – process of grouping things based on their similarities
2. Taxonomy – scientific study of how living things are classified
3. Dichotomous key – device for classifying organisms based on the answers to a
series of questions, with each question involving 2 choices
Classification system: Kingdom, Phylum, Class, Order, Family, Genus, Species
As you move down the classification system, organisms share more characteristics and
are more closely related
