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)
The nervous system communicates through electrical impulses and the communication is very fast. It works in a relay fashion, from point to point comparable to the way the old telephones systems used to work.
The endocrine system communicates by chemical signals via the bloodstream. Hormones are secreted into the blood and extra cellular fluids, then transported to target cells, which must bear a receptor to be able to bind to a specific hormone, and respond.
Hormones are chemical messengers secreted into blood or extracellular fluid that affect the function of other cells.
Endocrine communication is not quite as fast as the nervous system communication
I believe it is nervous tissue
