On the Origin and Diversity of Coelacanths (part 1)

An introduction to the Coelacanths great diversity.
Part 1: fossil record.
Part 2: genetic diversity of the extant Coelacanths
Messed up the references a bit...

Excellent vid. Very well researched and documented. Could've a little sound tho. But otherwise, first rate.

[Terrencje]

I will use sound in future videos

Still struggling with it tho :s

[Pitalla]

they should make special tanks in seaworld to have this guys.

So people can appreciate them and maybe have a breeding program.

brilliant video, a year back a creationist used this argument against me... I dont know much about animal diversity so I blundered through it... its good to see this up.

Bringing coelacanths near the surface kills them, it has been attempted before, and hasn't been possible. They are too used to the deep water pressure.

[JumpDeluxe]

A wellstructured video about the Coelacanths, provided with all the used scientific sources. Very nice!

Shame on you for using wikipedia though ;).

[LithodidMan]

Excellent, about time it has been said!

[truthofevolution]

I cant wait to see your video on the Lenski experiment.

[magick205]

I know. It's so hard to just get it out in the world; always want to fine tune it. I'm trying to work on a vid regarding the MSU Lenski lab's LTEE experiment. I just can't seem to express what I want without getting into jargon. Still, a very good vid. Keep it up.
