Description : I am studying the basics of Marine biology and have to ;
1) explain why there are so many species of fish
2) outline the potential explanations as to why fish show such high levels of diversification
3 ) evaluate the supporting evidence
Can anyone help me with this or send mea link to a site where I can find this kind of information.? So far I have evolution and environmental reasons but nothing in enough detail to really expalin!!
Thanks in anticipation
