Tiny chompers: How a baby Cichlid behavior influences an adaptive trait

Think of a trait, any trait. A bird beak, a butterfly wing, a fish fin. Highly coordinated gene expression networks ultimately produce all traits. Hence, any variation you see in these traits must be due to shifts in gene expression, whether that shift is determined genetically or by some external cue. Evolutionary developmental biologists want … Continue reading Tiny chompers: How a baby Cichlid behavior influences an adaptive trait
