Document Summary

Knowing the definition of an organism is important. Meaning one has to make accurate identification beyond superficial resemblance. E. g. with the mushrooms [all look the same but some are poisonous some aren"t] This is a challenge to biologist because they have to understand the significance of the similarities between theses species also their evolutionary history. Usually organism living in similar settings and have the similar lifestyles often resemble each other although they don"t have the same evolutionary history. Classification of organisms is based on evolutionary relationships using lots of evidence to prove it. Systematic biology, classification and taxonomy help us organize and understand information about the biological world. Knowing the identity of the organism of interest is the first step to finding out what is know about the organism. Science of systematics has 2 major goals. 1- is to reconstruct the phylogeny or evolutionary history of a group of organisms.
