Evolutionary Scientists
Proposed the idea of Descent with Modification
Charles Darwin
use of certain body parts is how parents pass physical traits to offspring
Artificial Selection
Change in genes of a population over time
Evolution
Population of organisms that can successfully reproduce
Species
Study of prehistoric life
Paleontology
Studied human populations
Thomas Malthus
organisms best suited for their environments reproduce more successfully
Natural selection
2 or more species in close association evolve together
Coevolution
Individual's genetic contribution to the next generation
Fitness
Movement of individuals into a population
Migration
Introduced concept called Deep Time
James Hutton
Terms that Darwin used to describe natural selection
Descent with Modification
environment selects similar features in unrelated organisms
Convergent
Reproductive isolation after fertilization
Postzygotic isolation
Study of geographical distribution of fossils and living organisms
Biogeography
Theory said organisms share common ancestors
Jean Baptiste de Lamarck
Two scientists who proposed the idea of natural selection at around the same time
Darwin and Alfred Wallace
related populations become more and more dissimilar
Divergent
Similar features with similar functions but anatomically very different
Analogeous Structures
Island where tortoises have sort necks and dome shaped shells
Isabella
Believed in idea of uniformitarianism
Charles Lyell
list the 4 types of selection
Sexual, Stabilizing, Directional, and Disruptive
Type of evolution that changes based on random events
Genetic drift
Features that were useful to an ancestor but are not useful to modern descendant
Vestigial Structure
Galapagos Island where the giant tortoises have long necks and saddleback shaped shells
Hood Island
