Document Summary
Chapter 18 systematics: seeking order amidst diversity. Biological species concept millions and millions of species do not reproduce sexually, so we have to find another way to define what a species is. The biological species concept defines a species as members of populations that actually or potentially interbreed in nature, not according to similarity of appearance. Although appearance is helpful in identifying species, it does not define species. Taxonomy is the branch of biology concerned with naming and classifying the diverse forms of life on our planet. There are many ways that things may be grouped: ex: plants verses animals: one of the early classifications placed the animals in one group and the plants in another. The bacteria, fungi and many protists were considered plants while some of the protists were grouped with the animals. Genius & species: ex: homo sapiens (humans); sciaenops ocellatus (red fish) Vertebrae are one of the major distinctions in the classifications of life.
