WebAbout this unit. This unit is all about evolution—one of the most important concepts in biology. Dive in to learn about the genetic, fossil, and anatomical evidence for evolution, and explore how natural selection shapes populations and group behaviors. Biology. WebApr 12, 2024 · With a rich foundation of studies on selection and phenotypic divergence, we reference the poison frog genus Oophaga to model signal evolution. Multifarious selection on aposematic traits created the topology of our model's fitness landscape by approximating different scenarios found in natural populations.
