In the process natural selection
Gene mutation

Radioactity, ultraviolet
Explained by biological evolution by natural selection
Fossils provide evidence of how earth's life change

Common Myths and Actual Reality
Fittest are those are most reproductively successful and leave most descendants
Evolution explain how species developed after life began
Human, apes and monkey evolved along different plath from common ancestor
Roles of species (niche) . One can play many roles
Native
Non native
Indicator
Keystone
Biodiversity
Functional Diversity
Species Diversity
Genetic Diversity
Ecological Diversity
Factors affect Biodiverstiy
By environmental conditions change
Human activities
By causing extinction of species
Through degradation of habitats
Artifical selection -> new species
By using genetic engineering to quickly manipulate genes
