For Poetic1 - clearing up a misconception.?

You mentioned in an answer that science has proven that there is a heartbeat 15 hours after conception.A 15 hour old fetus is a cluster of undifferentiated cells - the heart has not even FORMED. So there is no heartbeat yet. You need both a heart and a circulatory system for that to occur.
Week 3
beginning development of the brain, spinal cord, and heart
beginning development of the gastrointestinal tract
--------------- You get heartbeats around week 4 or 5.Don't define "life" in terms of heartbeat. Besides - there are creatures that don't even have hearts. heartbeats, or cirulatory systems in the insect world), but that doesn't mean they aren't alive.
Good for you for defending this! :-)
It's people like you that make Yahoo answers more and more appealing. I've found this too. . . people pulling "facts" out of their asses! And they are never around to be questioned.
Like those people saying " Science has no proof of evolution", and some more ridiculous ones like "Science has proved of God's existence" . .. tsk tsk tsk.
Are you answering something or asking something? What would you like to know?
