Meaning and Definition
The evolutionary process by which populations diverge to become distinct species.
The formation of new and distinct species in the course of evolution, often through reproductive isolation. Also used metaphorically in fields like technology or culture to describe the divergence of types.

FAQ
Frequently Asked Questions
No. Evolution is the broader process of change in heritable traits over generations. Speciation is a specific outcome of evolution where one lineage splits into two or more distinct species.
While the complete process is often too slow for direct human observation, many stages and examples of speciation (especially in rapidly reproducing organisms like bacteria or insects) have been documented and studied.
The primary driver is the evolution of reproductive isolation, which can be caused by various factors such as geographic separation (allopatry), ecological differentiation (sympatry), or genetic changes.
Yes, the verb is 'speciate', meaning to undergo speciation (e.g., 'The two populations eventually speciated').
The evolutionary process by which populations diverge to become distinct species.
Speciation is usually scientific/academic in register.
