Heart Advantage
Heart Advantage
What is the evolutionary advantage of a three chambered heart?
Doubt it. You may have noticed that there are fish which have a modified two-chamber heart that are larger and more populous than the non-crocodilian reptiles, and amphibians, which have three-chambered hearts.
The fish win. There are more species, and more individuals, of them than there are of three- and four-chambered hearted vertebrates put together.
Bad question. Bonk your teacher with a clue bat. Your teacher probably wants some guff like
"This circulatory system provides high pressure blood to the body, in addition to the respiratory organs, which can result in an ability to grow larger, blah blah blah.
Like I said, it's hooey, since big fish win.
