The genomes of living animals are littered with DNA from long-gone relatives, providing a lens on evolution, past extinctions, and perhaps even solutions to agricultural problems.
Immunoglobulin genes might have evolved much earlier than previously expected, perhaps even in the common ancestor of Cnidarians and Bilateria, a study suggests.
A high school student uses crowdfunding to produce the first genome assembly for this popular aquarium species, underscoring the increasing feasibility of whole-genome sequencing.
