O knihe
Macroevolution is a scale of analysis of evolution in separated gene pools. Macroevolutionary studies focus on change that occurs at or above the level of species, in contrast with microevolution, which refers to smaller evolutionary changes (typically described as changes in allele frequencies) within a species or population. The process of speciation may fall within the purview of either, depending on the forces thought to drive it. Paleontology, evolutionary developmental biology, comparative genomics and genomic phylostratigraphy contribute most of the evidence for the patterns and processes that can be classified as macroevolution. An example of macroevolution is the appearance of feathers during the evolution of birds from theropod dinosaurs. The evolutionary course of Equidae (wide family including all horses and related animals) is often viewed as a typical example of macroevolution. The earliest known genus, Hyracotherium (now reclassified as a palaeothere), was a herbivore animal resembling a dog that lived in the early cenozoic. As its habitat transformed into an open arid grassland, selective pressure required that the animal become a fast grazer.
