O QUE SIGNIFICA SPECIATION EM INGLÊS
Especificação
A especiação é o processo evolutivo pelo qual surgem novas espécies biológicas. O biólogo Orator F. Cook parece ter sido o primeiro a representar o termo "especiação" para a divisão de linhagens ou "cladogênese", em oposição à "anagênese" ou "evolução filética" que ocorrem dentro de linhagens. Se a deriva genética é um contribuinte menor ou maior para a especiação é o assunto de muita discussão em andamento. Existem quatro modos geográficos de especiação na natureza, com base na extensão em que as populações especificantes são isoladas umas das outras: alopatric, peripatric, parapatric e sympatric. A especiação também pode ser induzida artificialmente, através da criação de animais, agricultura ou experimentos de laboratório. Os exemplos observados de cada tipo de especiação são fornecidos ao longo de todo.
definição de speciation no dicionário inglês
A definição de especificação no dicionário é o desenvolvimento evolutivo de uma espécie biológica, como por isolamento geográfico de um grupo de indivíduos do estoque principal.

Although several excellent symposium volumes have recently appeared, these collections do not provide a unified, critical, and up-to-date overview of the field. Speciation is designed to fill this gap.
Jerry A. Coyne, H. Allen Orr,
2004
Unraveling the origin of biodiversity is fundamental for understanding our biosphere. This book clarifies how adaptive processes, rather than geographic isolation, can cause speciation.
The book begins by clarifying what ecological speciation is, its alternatives, and the predictions that can be used to test for it.
