Cards in this deck (7)
- 1OverproductionMore offspring produced than will ultimately survive and reproduce.
- 22. VariationInheritable features vary from individual to individual.
- 33. Change in environmentChanges in climate, topography, food supply, predators, etc.
- 44. "Survival for existence"Mainly competition within the species, for food, habitat, survival from being eaten.
- 55. "Survival of the fit" (not necessarily the strongest)Those with more adaptive traits tend to survive longer and/or produce the most offspring; these are the naturally selected
- 66. Inheritance of "selected" featuresTraits involved are already inheritable, but may involve new combinations.
- 77. New species, better adapted to the new environmentWhen the collective traits of the environment differ significantly from the earlier population, and can no longer reproduce with the earlier population.
