i doubt this is an original idea but the way i thought of it the other day seemed new to me.

so, which came first; the blood, the blood vessels, or the heart?

seems like a fair question to me. anyone know the answer?

lets understand something here.. this question "about egg / chicken" is a riddle not in fact a question

What came first the chicken or the egg:


the first word is your answer


hope that helps

I figured they all evolved simultaneously, natrually growing larger and more sophisticated. From a single cell organism, to the human body now. Over time it grew in complexity, if you look at it the way it is now, it would seem impossible that they would come together so perfectly, but over millions of years the change and growth would be natural and simple.

Id say plant first developed channels to carry water and nutreints up stocks. The heart is probobly just a modified propultion device, becuase in the water you needed to move to breath.....

These mutations came together in a fation that it survived in its habitat.

Answer: The dinosaurs.

Blood first. Even the simplest single-celled organism contains fluid in which the chemical processes of life take place.

Blood vessels second. Some primitive animals have blood, but no hearts.

Hearts last.

As for the chicken/egg question: the egg came first, obviously.

so there are creatures that have circulatory systems with no hearts. that's somethin else.

does anyone think it's possible that dna replicates things on a small scale as a test and then "picks" a winner?

maybe the dna creates only a handfull of cells in different ways to see what happens.

i'm just not sure i buy the "it works out all nice and slow" over time thing. cause really you're just going to chase the point back to teh big bang. surely there's room for more option than that.
