Charles Darwin Wrote a book called “On the Origin of Species” in 1859.

THE THEORY OF EVOLUTION IS THE IDEA THAT ANIMAL AND HUMAN LIFE HAVE DEVELOPED GRADUALLY OVER MILLIONS OF YEARS.

EVOLUTION Example of CLADOGRAM

Charles Darwin: “On the Origin of Species by Means of Natural Selection”

5.4.1 Define evolution.

Populations tend to produce more offspring than the environment can support. The consequence of the potential overproduction of offspring is a struggle for survival.

Members of a species show variation.

So.. what is natural selection??? ion.swf

WRONG! There are many “details” or evidences! The evidence for evolution is provided by the fossil record, selective breeding of domesticated animals and homologous structures. hill.com/sites/ /stud ent_view0/chapter23/animation _-_phylogenetic_trees.html

ANIMATION: ct.html

Explain two examples of evolution in response to environmental change; one is antibiotic resistance in bacteria. Can we see evolution today????? YES!!!! nfocus/antibiotics/antibiotics_fla.html

5.4.8 Explain two examples of evolution in response to environmental change; one must be antibiotic resistance in bacteria.

Animation of Evolution!

5.4.6 Explain how sexual reproduction promotes variation in a species

5.4.7 Explain how natural selection leads to evolution.
