How does microevolution differ from speciation?

When two isolated populations of the same species give birth to two distinct species, this phenomenon is known as speciation.

Speciation is thought to be the connection between microevolution and macroevolution. Microevolution is all about how populations differ from one another.

I hope it's helpful.

Microevolution refers to small-scale changes in the gene pool of a population over successive generations, such as changes in allele frequencies or the emergence of new traits. Speciation, on the other hand, is the process by which new species arise from existing ones, usually through reproductive isolation and the accumulation of genetic differences between populations. While microevolution primarily involves changes within a population, speciation involves the formation of distinct species through reproductive barriers.
