Document Summary
The discipline within biology that is concerned with : inferring the evolutionary relationships among organisms- phylogeny reconstruction, organizing and naming taxa- classification, study that establishes rules of classification- taxonomy. Schools of biological classification: phenetics, classifies species based on overall similarity, not concerned with phylogeny, earliest approach, but now uncommon, linnaeus" hierarchical classification; humans, kingdom-anamalia, class- vertebrata, order- primates, genus- homo, species- sapiens. ***why a feature might look similar in two species: Focuses on the relationship between: behaviors, natural environment, biological traits. Based on the assumption: animals, plants, and microorganisms evolved together. Some behaviors: influenced by genes, subject to natural selection. What you eat is determined by where you live. Niche: the sum of the habitat requirements that allow a species to persist and produce offspring. Fundamental niche: the full range of environmental conditions under which an organism can exist. Realized niche: a portion of the fundamental niche that an organism actually occupies.
