Paralogs

Genes within the same organism that have evolved by duplication and may have different functions.

Gene Family

A group of genes sharing a common origin that typically encode proteins with similar functions.

Molecular Clock

A method used to determine time based on base pair substitutions. Molecular clocks use the rates of molecular change to deduce the divergence time between lineages in a phylogeny, for example. They work best when they can be “calibrated” with other markers of time, such as fossils with known ages and placements.

Synapomorphy
