The drivers of tropical speciation | Nature An alternative model posits that rather than being directly linked to landscape change, allopatric speciation is initiated to a greater extent by dispersal events, with the principal drivers of ... Dispersal in the Ordovician Speciation patterns and ... Speciation frequency was lower during the T1 and T2 time slices, but slightly higher during the T3 time slice. Speciation was limited to the four brachiopod clades within Laurentian basins during this time slice. Biogeographic patterns are similar to the overall patterns of the T3 time slice. Evidence for speciation by reinforcement Wikipedia Reinforcement is a process within speciation where natural selection increases the reproductive isolation between two populations of species by reducing the production of hybrids. Evidence for speciation by reinforcement has been gathered since the 1990s, and along with data from comparative studies and laboratory experiments, has overcome many of the objections to the theory.

History of speciation Wikipedia The scientific study of speciation — how species evolve to become new species — began around the time of Charles Darwin in the middle of the 19th century. Many naturalists at the time recognized the relationship between biogeography (the way species are distributed) and the evolution of species. The 20th century saw the growth of the field of speciation, with major contributors such as ... Different Patterns of Evolution dummies.com Groups of species undergo various kinds of natural selection and, over time, may engage in several patterns of evolution convergent evolution, divergent evolution, parallel evolution, and coevolution. Convergent evolution Convergent evolution is the process in which species that are not closely related to each other independently evolve similar kinds of traits. Divergent selection during speciation of Lake Malawi ... Repeated evolution of the same phenotypic difference during independent episodes of speciation is strong evidence for selection during speciation. More than 1,000 species of cichlids, 10% of the world s freshwater fish species, have arisen within the past million years in Lakes Malawi and Victoria in eastern Africa. Many pairs of closely related sympatric species differ in their nuptial ... A Combinatorial View on Speciation and Adaptive Radiation ... Speciation is often thought of as a slow process due to the waiting times for mutations that cause incompatibilities, and permit ecological differentiation or assortative mating. Cases of rapid speciation and particularly cases of rapid adaptive radiation into multiple sympatric species have remained somewhat mysterious. We review recent findings from speciation genomics that reveal an ... Analysing patterns of spatial and niche overlap among ... Main conclusions. Patterns of broad geographical overlap among Banksia species support a predominantly allopatric mode of speciation, combined with post‐speciation range drift. There is more evidence for niche conservatism than for rapid niche divergence among closely related species. Patterns of co speciation and host switching in primate ... Patterns of co occurrence of primate malaria parasites and hosts were comparable to those that have been observed in avian plasmodia at the family and the clade levels [9, 10]. Therefore, malaria parasites of vertebrates are generally conservative, and do not infect all potential hosts across wide phylogenetic distances. PLOS Genetics Speciation and Introgression between ... Author Summary While speciation is often depicted as a simple population split, in many cases it is likely more complex. Recently, whole genome sequencing and computational methods to interpret patterns of genomic variation have facilitated the inference of complex speciation histories.

The estimated speciation duration based on our result from the protracted speciation model was about 1 Myr (0.929), so the isolation time provided by sea level rise during the interglacial periods of the Pleistocene, which ranges in the tens to hundreds of thousands of years, may have been insufficient to complete speciation (see Papadopoulou ...
