This eventual process of speciation by natural selection is illustrated by a sketch drawn by Darwin in his personal notebook nearly 20 years before the Origin of Species was published (Figure 1).

The biological equivalent is "allopatric speciation," an evolutionary process in which one species divides into two because the original homogenous population has become separated and both groups ...

Taxonomic disagreement, they claim, is best explained by how the speciation process is modeled in the record, rather than conflicts between evidence types. The article "Homo sapiens, Neanderthals ...

This hypothesis predicts that the fossil record at any one site is unlikely to record the process of speciation. If a site records that the ancestral species lived there, the new species would ...

When organisms of the same species develop preferences for different traits and no longer breed with each other, new species could emerge over time, a process known as speciation. For the past 150 ...

I expect you to read: Avise, J.C. 2004. Chapter 7: Speciation and hybridization. In Molecular Markers, Natural History and Evolution (2nd edn.). Chapman and Hall, New York. Having at least briefly ...

Tukaram.Karve/ Shutterstock The definition of speciation is that it is the process by which new species form. When different populations of a single species are separated and can no longer interbreed, ...

Complete human, chimpanzee, bonobo, gorilla, and orangutan genomes have provided us a window into understanding the complex speciation process of these species' common ancestor. Analyses of these ...

Though once viewed as primarily antagonistic to the speciation process, hybridization is now increasingly viewed as widespread and playing a constructive role in adaptive evolution. Despite this, we ...

The evolutionary forces experienced by populations during the speciation process will influence its outcome. Understanding the impact of these forces helps to explain the patterns of biodiversity we ...
