Many groups of closely related species have reticulate phylogenies. Recent
genomic analyses are showing this in many insects and vertebrates, as well as\ in microbes and plants. In microbes, lateral gene transfer is the dominant
process that spoils strictly tree-like phylogenies, but in multicellular eukaryotes\ hybridization and introgression among related species is probably more\ important. Because many species, including the ancestors of ancient major\ lineages, seem to evolve rapidly in adaptive radiations, some sexual\ compatibility may exist among them. Introgression and reticulation can thereby\ affect all parts of the tree of life, not just the recent species at the tips. Our\ understanding of adaptive evolution, speciation, phylogenetics, and comparative biology must adapt to these mostly recent findings. Introgression has\ important practical implications as well, not least for the management of\ genetically modified organisms in pest and disease control.
