Recap on Evolution. What is the Theory of Evolution? Evolution is defined as change over time. One of the earliest theories of evolution was put forward.
SPECIATION Ch. 16-3 pp. 326-330 Warm up 2/25: Define: Homologous Structures, Analogous Structures and Vestigial Organs/Structures. Give 1 example of each.
Speciation The formation of a new species. Speciation- occurs in isolated populations Geographic isolation leads to reproductive isolation Once the population.
EVOLUTION! Summing it all up!. In science, theories are statements or models that have been tested and confirmed many times. What is Scientific Theory?
Evolution of a Species Changes to a gene pool can lead to the evolution of a new species Speciation = members of similar populations can no longer interbreed.
How can populations evolve to form new species or to eliminate a species?
