A population becomes separated by different environments and do not reproduce with one another.
It can be simple changes as environment and food that lead to speciation.
The climate of the area witch the species live in , the type of food that is at that area and if their are enough of those species to reproduce
Climate change
Adaptive change and speciation.
A population becomes separated by different environments and do not reproduce with one another.
Speciation can happen for a variety of reasons, but typically it's some sort of environmental change such as changes in relevant prey and other food sources, changes in the relevant predators, changes in the climate (i.e. temperature changes, rainfall changes, etc.), etc. Speciation or extinction will occur as the eventual result of any evolutionary dead end; though the creature may fail to adapt (aka evolve), the environment is going to change eventually.
Allopatric speciation and sympatric speciation are two factors. Allopatric speciation occurs when physical barriers are formed, separating the specie. This will cause the specie to evolve at different rates causing a new specie to form. Sympatric speciation is less likely to occur when comparing it to allopatric. In sympatric speciation is no longer physical but generic. For example a mutation in the genetic order of the specie (which does not happen as often as physical barriers), and a different mating preference/season.
Actually it is.

speciation
Species (phylogenetically and genetically distinct animals from a common ancestor) form when barriers exist to prevent outbreeding. These are usually environmental (e.g. mountain ranges, oceans, climatic barriers) or biological (e.g. interbreeding of two species results in an infertile offspring).
The development of a new species through evolution is called speciation.

Industrialization: The shift from agrarian to industrial societies brought about social changes that sparked interest in understanding society and social interactions. Urbanization: The growth of cities increased social complexity, leading to the need to study issues such as social order, organization, and change. Enlightenment thought: Philosophical ideas emphasizing reason, individual rights, and social progress influenced the development of sociology as a discipline focused on understanding human behavior and social structures.
