BI111 Lecture Notes - Lecture 3: Genetic Drift, Keratin, Parapatric Speciation
Document Summary
Carl linnaeus as the father of modern taxonomy and binary nomenclature: genus and species: life domain kingdom phylum class order family genus species. If individuals were in the same genus, they shared common ancestry. Species: a group of organisms that is biologically disinct from others and evolving along a family: there are at least 22 possible deiniions for a species. Species concept: way of describing a species, and how one can disinguish between species: do not only deine what a species is, but in doing so, they also deine what speciaion is. Important to many biologists working in the ields of: taxonomy, evoluionary biology, ecological and behavioural studies, conservaion biology. Organisms are classiied in the same species if they appear idenical by morphological (anatomical) criteria. Species delineaions based on notable diferences in phenotype: pros. A pracical approach that is widely understood by both scienists and non- scienists. Focuses on novelies that have arisen over ime (diagnosic characterisics)
