Document Summary
We can look at phenotype and measure similarities and differences -- we meansure distances. Will not cover ml and bi in this class. Systematic biology -- when taxonomy is performed. heuristically = practically. Assume we know same part of same gene and we can align it for cow and deer -- there"s differences at 73 sites -- known as hamming distance. A matrix of distances -- the common ancestor between the cow and the deer is 0. 075 distance -- milk protein gene beta-casein. Evidence/data = to create a classification/evidence to send organism into a taxa. The simplest explanation is usually correct. i. e. all vertebrates have a backbone. Represent the real things in the real world -- a character state is an organism either having the presence or absence of vertebrate. Can classify every animal on the planet this way.
