evolution and speciation
this process introduces new genetic variation into a population through mutation recombination and gene flow
What is genetic variation?
this concept defines species based on their ability to interbreed and produce fertile offspring
What is the biological species concept?
this type of evolution occurs when related species become more different over time
what is Divergent evolution?
These are offspring resulting from the mating of two different species, like a mule or liger.
What are hybrids?
These are the five agents of evolutionary change
This type of speciation occurs when populations are geographically separated.
What is allopatric speciation?
These four lines of evidence support the theory of evolution.
What are fossils, comparative anatomy & embryology, biogeography, and molecular biology?
These isolating mechanisms prevent mating or fertilization, or affect offspring viability.
What are pre-zygotic and post-zygotic barriers?
These structures share ancestry, function, or form—or have lost function entirely.
What are homologous, analogous, and vestigial structures?
This rapid diversification of species occurs when organisms colonize new environments.
What is adaptive radiation?
