Speciation

Speciation

Speciation. Speciation in Darwin’s Finches. Speciation in the Galapagos finches occurred by founding of a new population, geographic isolation, changes in the new population’s gene pool, reproductive isolation, and ecological competition. Founder’s Arrive.

Conservation Genetics

Conservation Genetics

Conservation Genetics. Why should we be concerned with genetic diversity when more severe threats threaten entire systems? First , the rate of evolutionary change in a population is proportional to the amount of genetic diversity available Fundamental Theorem of Natural Selection.

Gene and Chromosomal Mutations

Gene and Chromosomal Mutations

Gene and Chromosomal Mutations. What is a mutation?. Mutations are changes made to an organism’s genetic material. These changes may be due to errors in replication, errors during transcription , radiation, viruses and many other things.

The Origin of Species

The Origin of Species

The Origin of Species. Patterns of Speciation. Fossil record indicates two patterns: anagenesis (phyletic evolution) - an unbranched lineage cladogenesis -branching evolution most commot form promotes greater diversity by increasing the number of species. Patterns of Speciation.
