what the universe is macro-evolution?

Answer 1

Macroevolution refers to evolution that occurs above the level of species, over long periods of time, that leads to speciation, in contrast to microevolution, which refers to smaller evolutionary changes (described as changes in allele frequencies) within a species or population. Within the Modern Synthesis school, microevolution is thought to be the only mode of evolution. The process of speciation (in isolated populations) can fall within the purview of either. Paleontology, evolutionary developmental biology, and comparative genomics contribute most of the evidence for the patterns and processes that can be classified as macroevolution.

Macroevolution is controversial in two ways:

It is disputed among biologists whether there are macroevolutionary processes that are not described by strictly gradual phenotypic change, of the type studied by classical population genetics. One of these two views is becoming less and less tenable as the role for genome-wide changes and developmental processes in evolution become clearer.
A misunderstanding about this biological controversy has allowed the concept of macroevolution to be coopted by creationists. They use this controversy as a supposed "hole" in the evidence for deep-time evolution.

Answer 2

To simplify it macro-evolution is when one species evolves into another. For example apes to humans. Where as micro evolution is when with in a species there are small changes that help the animal adapt to it's environment. For example some birds have got a longer beak than others that are the same species. Micro evolution is the only form of evolution that has ever been observed.
