When particles spread out it is called diffusion.
This is a song about adaptation not classification,
with cladograms you dont know whats up,
in your domain its your kingdom.
think about fitness, try evolution,
like a pokemon abra into kadabra.
like a fossil of areodactyl,
going into extinction.
homology try taxomony
with your mind your not a phony.
genetic variation with genetic equilibrum,
Go hand in hand cant even believe them.
genetic variation cant get left out,
truthfully you cant go without.
Natural selection in speciation
dont even know how to go with the flow.
P.S : i made this up as i went (please like it)
