idea that a species is a population or group of populations whose members have the ability to breed successfully in nature but not to interbreed successfully with members of other species | ||
Model of evolution in which long periods of little change in a species are broken by shorter times of more rapid change | ||
Scale that organizes Earth's history into four eras | ||
Method of dating fossils based on radioactive isotopes | ||
Diagram that reflects hypothesized evolutionary relationships | ||
Process in which unrelated species from similar environments have adaptations that seem very similar | ||
Homologous structure that does not occur outside a particular clade | ||
Process in which new species form | ||
This event occurs when some kind of reproductive barrier develops that prevents interbreeding | ||
Huge numbers of species going extinct in a short period of time | ||
Surviving species becoming more diverse as they adapt to new environments | ||
Occurred at the end of the Paleozoic Era; results in the supercontinent | ||
Condition that may be either geographic or reproductive | ||
Process results in new species | ||
Scientists study the development of organisms | ||
Example of this is speciation | ||
Diagrams based on derived characters | ||
Two names | ||
Science that classifies organisms | ||
Taxonomic category that is broader than a kingdom | ||
Both homologous and analogous forms of these result from evolution |
