macroevolution changes :
that occur above the species level over long periods of time
↳ remarkable trends and transformations
microevolution : occur within species ,
smaller , gradual changes within a population or a species over long periods of time
phylogeny scientific study : of evolutionary relationships among species
Phylogenetics :
study of the evolutionary relationships among groups of organisms which have been discovered
through lines of evidence
