Speciation - Wikipedia
Speciation is the evolutionary process by which populations evolve to become distinct species. The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages.
Speciation | Causes, Process, & Types | Britannica
speciation, the formation of new and distinct species in the course of evolution. Speciation involves the splitting of a single evolutionary lineage into two or more genetically independent lineages. (Read E.O. Wilson’s Britannica essay on mass extinction.)
Speciation - Definition and Types - Biology Dictionary
2019年3月28日 · Speciation is a process within evolution that leads to the formation of new, distinct species that are reproductively isolated from one another.

2023年8月3日 · What is Speciation? Definition, causes, process, types (Allopatric, Peripatric, Parapatric and Sympatric Speciation) and examples.
Speciation: The Origin of New Species | Learn Science at …
Like most areas of Evolutionary Biology, research related to the formation of new species - 'speciation ' - is rich in historical and current debate. Here, we review both early and modern views...
Speciation – Definition, Types, Phases, Causes, Examples, & Diagram
2024年10月4日 · Speciation is an evolutionary event through which new species arise from preexisting ones. It occurs when a group of members within a species becomes isolated, develops unique characteristics, can no longer interbreed with other members of the population, and evolves independently over time.
Speciation - Definition, Causes, Types, Process - Biology Notes …
2024年10月25日 · Speciation is the evolutionary process through which new, genetically distinct species arise from an existing species, often due to reproductive isolation and genetic differentiation between populations. This can occur via mechanisms such as allopatric or sympatric speciation.
Types of Speciation and Their Biological Processes
2024年10月20日 · Speciation, the process by which new species arise, is a fundamental concept in evolutionary biology that contributes to biodiversity. Understanding how speciation occurs helps us comprehend the mechanisms driving evolution and adaptation across different environments.
11.4: Speciation - Biology LibreTexts
2021年9月22日 · Speciation occurs along two main pathways: geographic separation (allopatric speciation) and through mechanisms that occur within a shared habitat (sympatric speciation). Both pathways force reproductive isolation between populations.
Species - Speciation, Variation, Adaptation | Britannica
5 天之前 · Species - Speciation, Variation, Adaptation: Subspecies are groups at the first stage of speciation; individuals of different subspecies sometimes interbreed, but they produce many sterile male offspring.
