Document Summary
Macroevolution large scale changes at or above the species level, extending over geological era, and resulting in the formation of new taxonomic groups. Speciation evolutionary process involving the formation of a new species. Individuals can vary greatly yet still be considered one species (dogs) Typological species concept similar-looking individuals lumped into discrete categories. Modified typological species concept similar-looking individuals that can successfully produce fertile offspring lumped into discrete species categories. Individuals are the same species if they can successfully produce fertile offsprings (no longer favoured) because . Erroneous conclusion that males of the same species, or conspecific males, represent different species (two males cannot reproduce) Distinct species can reproduce to form hybrids. There are two definitions of species, which has a strong relevance to evolutionary anthropology: biological species concept (bsc) Introduced by geneticists and researchers who study the diversity of life. Traits may be shared between different species. One species cannot breed with another species.
