Document Summary
Evolutionary processes: def: explanation of a natural phenomenon based on many observations and investigations over time. Pattern facts that we see out there. Process mechanisms that produces the patterns: on the origin of species (1859, all life evolved gradually from one primitive species [lived 3. 5 billion years ago] Split off into many diverse species over time. Gradually because it takes generations to produce evolutionary change: descent with modification. Pattern of evolution: the fact of evolution that we see and notice different things. A group of individuals of one species living in a particular place. Microevolution: the change in allele frequencies in a population over time: trait or character: heritable feature that can be observed. Behavioral: ability to learn something, food searching. Inherited characteristics in a population of a species change over time. Sometimes population changes over time to form a new species. Pattern of evolution: the fact of evolution that we see and notice different things: population:
