How much of any genome is functional? In this video, I review the definitions of "function", different type of genomic elements relative to their functionality, introduce selection-drift antagonism, and present the intuition for methods for detecting sequence constraint. Ultimately, I conclude that the percent of functional elements is inversely proportional to the size of the genome.

![Demystifying Evolutionary Biology: My Summer Plans
Welcome to the channel! Im Zach Hancock, an evolutionary biologist who specializes in population genetics, phylogenetics, and genome evolution. This summer, Im embarking on a new project focusing on the spatial genetics of beach moles (small crustaceans that live on sandy beaches), and Im bringing you along for the ride! I will be filming the whole study, from beginning to end, and this project will serve to demystify evolutionary biology for the general public. Hope youll stick around for it! In the meantime, enjoy the other content on the channel that ranges from evolution education, pseudoscience debunking, and invertebrate systematics.
