The species definition turns on FERTILE offspring — that is what keeps species separate in nature.
What this lesson covers
Challenges to clear
- Match every term.
- Connect species to its definition — the fertile-offspring test is the whole point.
The task
Match each term to what it means.
What this lesson covers
- Species — A group of similar organisms that can interbreed and produce fertile offspring (Fertile is the key word — a horse and a donkey interbreed, but the mule is sterile.)
- Genus — A group of closely related species (Panthera contains the lion, tiger and leopard.)
- Taxonomy — Identifying, naming and classifying organisms (Taxis = arrangement, nomos = law.)
- Systematics — Classification based on evolutionary relationships (It asks not just how alike organisms are, but how closely related.)
- Taxon — Any group at any rank in the classification (Mammalia is a taxon; so is Panthera.)
- Hierarchy — Ranks arranged one inside another, from broad to narrow (Each level contains all the levels below it.)
Hint
The species definition turns on FERTILE offspring — that is what keeps species separate in nature.
