Evolution reproduced in the lab or documented in nature:
a. Two strains of fruit flies lost the ability to interbreed and produce fertile offspring in the lab over a 4-year span ... i.e. they became two new species. (Easily repeated experiment.)
b. A new plant species (a type of firewood), created by a doubling of the chromosome count from the original stock (Mosquin, 1967).
c. Multiple species of the house mouse unique to the Faeroe Islands occurred within 250 years of introduction of a foundation species on the island.
d. Formation of 5 new species of cichlid fishes that have formed in a single lake within 4,000 years of introduction of a parent species.
