The evolution of the African coelacanth

Recommended Posts

Eldorado

The coelacanth, a fish that scientists once thought extinct for 65 million years, had more surprises in store as researchers discovered the modern-day species picked up 62 new genes throughout its long, mysterious history.

Dubbed a “living fossil” when it was captured off the coast of South Africa in 1938 because it looked anatomically identical to its fossil record, the mighty ocean predator coelacanth had another surprise in store.

In a study published Tuesday in the journal Molecular Biology and Evolution, scientists detailed how the African coelacanth picked up new genetic material through its interactions with other fish approximately 10 million years ago. So while its body has changed very little in 65 million years, genetically it’s a different creature.

I didn't know that there is ancient DNA to compare to the current.

Hasn't this been known for a long time? 

I remember posting differences in the fins skeletal structure here years ago.

Coelacanths are such awesome creatures... Sort of reminds me of this video. I think I saw something on the tv about a neighborhood that had gotten flooded with catfish walking their streets. A bit unrelated, but...
