Spontaneous generation, all cells arise spontaneously from non-living material. 7. Define: Heritable trait, Adaptation, fitness. Heritable trait- characteristics that can be passed on to offspring. Adaptation- a trait that increases the fitness of an individual in a particular environment. Fitness- the ability of an individual to produce surviving fertile offspring. 8. How does artificial selection differ from natural selection? Artificial selection is deliberate manipulations by humans by allowing only the desirable individuals to reproduce. Natural selection occurs when heritable variation in certain traits leads to an improved success in reproduction. Chapter 23: 1. Who is the father of modern Taxonomy? Carolus Linneaus 2.
