Phylogeny
uses communal ancestry to group organisms and further nest them into bigger and
bigger groups. This is also a study of evolutionary relationships among
organisms. Visible characteristics such as anatomical and behavioral traits, as
well as biochemical (enzymes, proteins, pigments, etc.) and genetic traits
(nucleotide sequences) that need more modern techniques to detect.
The different biochemical characters such as enzymes, pigments and proteins among species can be used to determine patterns of phylogeny
through the comparison of the similarities and differences between the DNA in
two groups that serves to establish homologous or ancestral relationships.
Reproductive technologies benefited agricultural industries by fulfilling humans needs such as food. An example of this would be breeding cows for milk or meat.
