Document Summary
Microevolution & macroevolution: evolution under domestication, fossil record, similarity of characteristics, species change by natural selection. Process: maintenance / change in traits over few. Pattern: origin of species or higher taxonomic generations groups, origin / change in traits that define new taxa, occurs within species, current fitness effects, ecological time scales (few generations) Microevolution: evidence that selection can produce evolutionary change, evidence that species change through time. Macroevolution: evidence that ancestral species can give rise to diverse descendants, history / sequence of change, geological time scales (thousands/millions years) Humans have been using selective breeding to change the traits of organisms for more than 10,000 years. Domestication is when we breed something to have characteristics that we can use and it becomes associated with us over long periods of time. Evidence of sustained interaction of availability of that plant or animal with human population, humans have domesticated them.
