Topic (32) Construct an explanation about adaptations resulting from natural selection. (HS-LS4-4)
Animals are multi-cellular, eukaryotic organisms. Animals form the biological kingdom Animalia. Animals consume organic material, breathe oxygen, are able to move. Animals reproduce sexually, and grow from a hollow sphere of cells (the blastula) during embryonic development.
Over 1.5 million living animal species have been described—of which around 1 million are insects—but some scientists estimate over 7 million animal species in total. Animals range in length from 8.5 millionths of a meter to 33.6 meters (110 ft) and have complex interactions with each other and their environments. Animals form intricate food webs. The study of animals is called zoology. (source)
