Micro evolution can lead to macroevolution
Yes. In fact, microevolution, or allelic variance, is the mechanism by which new species emerge. Such an emergence is part of what some people call macroevolution. In other words, microevolution is the mechanism by which macroevolution is produced.
Microevolution is small evolutionary changes. Macroevolution is change above the specie level. Biologists debate if this process even exists. Some say they are fundamentally the same thing. It seems that macroevolution is the evolution of evolution. That sounds complicated.
Speciation is an example of macroevolution. The slow transition of land tetrapods to whales, the transition of small, many toed creatures into horses. These are not linear so much as branching progressions with the occasional dead end. Darwin's finches are a modern example of macroevolution by adaptive radiation.speciationBirds are reptiles.
