Scientists sequence the coelacanth genome

Referred to as a 'living fossil', the coelacanth has barely changed at all in over 300 million years.

Thought to have become extinct during the Cretaceous period, the coelacanth amazed everyone when a live specimen was caught off the coast of South Africa in 1938. More amazing still was the fact that despite being around for millions of years the species shows very little in the way of evolutionary change. The term 'living fossil' was coined to describe creatures that fit in to this category.

To learn more about the coelacanth, an international team of scientists has managed to sequence the animal's genome which contains almost three billion DNA bases. "What we can see is that while the genome as a whole changes, the protein-coding genes - that make the living fish - are much more stable and much more unchanging," said Professor Kerstin Lindblad-Toh. "It lives several hundred metres down in the ocean, and it may also be in an environment where it doesn't have a lot of competitors. So maybe it adapted to that environment a long time ago and it doesn't have a huge need for change."

"The genetic secrets of a "living fossil" have been revealed by scientists."

This is one of the many examples of the theory of evolution.It doesn't exist as far as I believe.As one of our regular readers suggested before,"If Man was once ape,then why are there still apes & human beings?" That was well said! Oh,and I love Billy Connolly too. lol XOXOXO

PLEASE...not another one.BTW I saw a really cool ( for a 10 year old boy) movie once about a Coelacanth. A scientist was studying the thing in a lab and a dragon fly landed on it for a snack - voila'!! A giant dragon fly enters the picture. the 1960's were a cool time to be a kid

it would seem no evolution on this fish took place because it had no need to evolve. Does that sound good?

it would seem no evolution on this fish took place because it had no need to evolve. Does that sound good? That is what they are theorizing and I am sure there are many more abyss dwellers that have been around in the same form for millions of years.
