Phylogenetic classification has two main advantages over the Linnaean system.
-First, phylogenetic classification tells you something important about the organism: its evolutionary history.
-Second, phylogenetic classification does not attempt to "rank" organisms.
Linnaean classification "ranks" groups of organisms artificially into kingdoms, phyla, orders, etc. This can be misleading as it seems to suggest that different groupings with the same rank are equivalent.
Meiosis actually combines the genetic components from two people and doesn't result in a genetic copy of either parent, and each child receives different genes from each parent. It creates genetic diversity among species instead of every member of a species having identical genes.
