Why common names are bad?

This article explores the complexities of common names in zoology, highlighting how one species can have multiple names across different regions, such as the Moose in North America and Elk in Europe (Alces alces). It discusses the implications of using misleading names, such as the Emperor and Adelie Penguins, which may confuse identification. We also delve into the principles of taxonomy, including binomial nomenclature established by Carl Linnaeus. Understanding these concepts is crucial for accurately classifying and studying organisms, helping us improve communication in biological sciences.

  6. TAXONOMY Study of the principles of classification of organisms • Aristotle (2000 yrs ago) • Plants vs Animals • Greeks/Romans • Basic categories • Dogs/Horses/Cows/Trees • Carl Linnaeus • Binomial nomenclature

  7. Review of Nomenclature • Carolus Linneus • Two name • Genus (capitalized) species (not capitalized) • Examples: Homo sapiens, Bos taurus • After mentioned, abbreviated with the initial of the genus and the full species name. • Examples: H. sapiens, B. taurus • Except when it is as the beginning of the sentence

  8. TAXONOMY Domain: Eukarya (eukaryotes) Kingdom: Anamalia (animals) Phylum: Chordata (animals with spinal cords) Class: Mammalia (warm-blooded animal whobears its young live) Order: Primates (includes: humans, apes, monkeys, gorilas, etc) Family: Hominidae (hominids, us, chimps, gorillas) Genus: Homo (family of man,predecessors) Species: Homo sapiens (You and me)
