@camhenry72 Microevolution is the change of allele frequencies from one generation to the next, but not changes over extremely long periods of time (millions of years) and changes leading directly to speciation.

Macroevolution are changes that lead directly to speciation and typically viewed as long term changes, like over millions of years.

That should help.
