extinction
A mass extinction.
The process in which groups of organisms die out is called extinction. Extinction occurs when a particular species cannot adapt to changing environmental conditions or faces competition from other species, leading to their eventual disappearance.
The process in which new organisms replace those that die is called succession. It involves the gradual change in the species composition of a community over time, with new species colonizing an area after the previous ones have died or been removed. This process often leads to the establishment of a stable and diverse ecosystem.

The term used to describe the process for a new species developing from an existing species is "speciation." This process occurs when a population becomes reproductively isolated from the original species, leading to the accumulation of differences over time that eventually result in the formation of a distinct new species.
evolution
a new species arises or forms!
As they live the organisms comprising a species will age and die, they therefore need to reproduce (have babies) in order to replace the members of the species that die or the species will cease to exist (become extinct).
That process is called Speciation!

evolution
The slow process that results in new species is called speciation. This occurs when a population of a species becomes isolated from the rest of its species and over time, genetic mutations and natural selection cause it to evolve into a distinct species. This process can take thousands or even millions of years to be completed.
