Charles Darwin (1809-1882)

The Voyage of the Beagle and Galapagos Islands (1831)

Theory of Evolution Organisms change gradually over time by adapting to their environment through natural selection. Also created the tree of life, where all organisms share a common ancestor Actually, his main contribution was NATURAL SELECTION!!!

Proof for Evolution Fossils (rock record) Adaptations through natural selection Embryo development Homologous structures (bones) DNA relationships (genetics)

Fossils

Embryo development

Natural Selection Mechanism that allows one trait with an advantage for survival in an environment to be passed on to the offspring. Survival of the fittest!

Homologous Structures (bones) Same structure, different function
