More advanced research methods have allowed scientists to classify species based on genetics, cellular morphology, and molecular chem. In the past, scientists were limited to classifying organisms according to morphology(physical/anatomy). Thanks to our current understanding, biologists today are able to revise the status of current species, and also to study the evolutionary relationships between species and groups of organisms

Genetics! We can now classify things on their genetic family groups rather than on their morphology.

We can compare the DNA. More closely related species have more similarities in the DNA.
