New genes that have evolved in species as little as one million years ago -- a virtual blink in evolutionary history -- can be just as essential for life as ancient genes, startling new research has discovered.

What's The Difference Between Mice And Men? (Nov. 14, 2006) It's often said that a man shares 30% of his genes with a banana, rather more with a fruit fly, and yet more with a mouse; so why are these organisms so different if many of their genes are so ... (WOW! this is something to think about - EVOLUTION!)

Just shows that the more we know the less we know. It is dangerous to make assumptions without proof in science. Thanx Nancy, you find some great articles.

This just proves how we are all connected and that we need to care for everything because in doing so we are taking care of ourselves, too. Amazing how events can change the evolution of a species.

Maybe now they'll concentrate on labratory testing on genes & not rely on animal sacrifices!
"As such, a full understanding of biological diversity may require a new focus on genes unique to each organism.
"I think it has important implications on human health," Chen said. "Animal models have proven to be very useful and important for dissecting human disease. But if our intuition is correct, some important health information for humans will reside in the unique parts of the human genome."
