Mechanism that drives evolution
WebGenetic transmission is the mechanism that drives evolution. DNA encodes all the information necessary to make an organism. Every organism’s DNA is made of the same basic parts, arranged in different orders. DNA is divided into chromosomes, or groups of genes, which code for proteins. WebApr 14, 2024 · Interactions between species have catalyzed the evolution of multiscale ecological networks-including both nested and modular elements that regulate the function of diverse communities. One common assumption is that such complex pattern formation requires long evolutionary timescales, spatial isolation, or other exogenous processes. …
