Document Summary
Communication affects both inter and intraspecific behavior: like monkeys signaling for eagle or leopard. Names to distinguish between categories of objects: each species has a scientific name. Latinized descriptions of the organism bearing the name. Biologists use names to precisely identify species, subspecies, or varieties traditionally, morphological features were most important to identify species, but now behavioural and genetic features are more commonly used. Molecular markers are also becoming important to identify and separate species. Species = a latin word meaning kind or appearance . Species are the fundamental taxonomic units of biological classification. Biological species concept defines species as group of organisms that can successfully interbreed and produce fertile offspring but are unable to produce viable fertile offspring with members of other populations: problems. Works with sexually reproducing species, does not work with those that reproduce asexually species that hybridize and produce fertile offspring. Hybridization: two species interbreed and produce fertile offspring.
