Document Summary

Structural or behavioural similarities (in terms of functions) shared by unrelated species or organisms but do not share a common ancestry/developmental origin; analogous. This is the most available carbon source, where it exists as ions in the ocean. Interface between carbon dioxide and water in the ocean creates bicarbonate. There is a constant rain of insoluble carbonate salts that are falling to the bottom of the ocean; this is how sedimentary rocks form fossils (traps living organisms) As water levels in the oceans rise, the bicarbonate levels rise as well. When life developed a pathways that allowed them to absorb calcium from the oceans and allowed them to put it in the matrixes of shells and bones, more complex organisms started to develop. Founded by leclerc; the study of the geographic distributions of plants and animals. Continuous distribution: when many species live in suitable habitats throughout large areas. Disjunct distributions: when species live in widely separated locations.
