Document Summary
Sometimes populations are genetically similar but they were separated we wouldn"t be able to do this in biological concept: they are a disjunct population/gene pool and cannot breed in nature (thus not species) Cryptic: hard to gure out or see: we call the cryptic species bc hard to tell the difference. The damsel ies: need to look at complicated genital to identify. A and b species are the same species: both are non-vinomous, the other two are poisonous, a and b are mimics of c and d. Mimicry has lead to a convergence of patterns: this is when to separate gene pools converge to a similar phenotype, can add a very recent fork between the two milk snakes. They can still bred where the two habitats meet. A lot of what we know from past species are from genetics (sometimes) and fossils (for ancient things) Some recent fossils can get dna from it.
