Best known for establishing the theory of organic evolution by natural seletion

He was born in Shrewsburg, England the son of a respected physician. Born on February 12, 1809

Darwin developed a scientific theory of biological evolution that explains how modern organisms evolved over long periods of time through descent from common ancestors.

Planned to collect specimens of plants and animals. This is one of the most important scientific voyages in history because the Beagle tripled Darwin to develope what has been the single best idea anyone has ever had.

Species vary globally
Species vary locally
Species vary over time

Some fossils didn't take anything like living organisms but others did. Darwin noticed that some fossils extinct animals were similar to living species many recently discovered fossils form species that trace the evolution of modern species from extinct ancestors.

An idea called descent with modification impulse that life has been on earth for a very long time.

Consist of two twisted polymeric strands made up of mononucleotide units. Each nucleotide is composed of all three seperate parts a 2-deoxyribose sugar, a phosphate, and one of the floor base A-T, C-G Double helix.

Not all homologous structure have important functions. Vestigial structures are inherited from ancestors but have lost much or all of their original functions due to different selections pressures acting on descendant.

Valcanic forces have altered landscapes over much of earth even producing entire islands that provide new changing climates and geological forces have attracted habitats of living things. Continents have collided to form super continents and then drifted apart.

Directional selection is when individuals at one end of the curve have higher fitness

Process by which organisms with variation most suited to their local enviorment survive and leave more off springs on polygeneric traits can affect the relative fitness of phenotype and theory produce one of three types of selections directional disruptive, or stabilizing. Evolution fitness as sucess in passing genes to the next generation.

Darwin noticed that different yet ecologically similar animal species inhabited, separated but ecologically similar habitats around the globe. Darwin noticed that different yet related, animal species occupied different habitats within a local area. Darwin noticed that some fossils of extinct animals were similar to living species.

Some of the tortoises Darwin discovered were very huge as to some that were medium sized. There are different behaviors in the tortoises some move slower than other.
