Algae held captive and genes stolen in crime of evolution
Date:11/28/2012

Microscopic animals held algae captive and stole their genes for energy production, thereby evolving into a new and more powerful species many millions of years ago reveals a new study published today in the journal Nature.

The results reveal a 'missing link' in evolution because the tiny animal thieves (protozoa) couldn't completely hide all evidence of the captive algae, and have been effectively frozen in time and caught in the act by genetic sequencing.

The protozoa captured genes for photosynthesis- the process of harnessing light to produce energy which is used by all plants and algae on earth - so the study also provides insight into the origin and repurposing of these genes and may be useful in algae biofuel production.

The work was conducted by an international team of researchers led by Dalhousie University in Canada and included Professor Geoff McFadden from the University of Melbourne.

Professor McFadden from the School of Botany said that scientists had long suspected that quantum leaps of evolution occurred by one organism cannibalizing another, but we did not have much hard evidence.

But when they looked at two specific algae- Guillardia theta and Bigelowiella natans- the team realized the evolution was not quite complete. They could see that their cells had two nuclei (like the control centre of the cell that contains DNA). This is unusual because plant and animal cells only have one, so the genes were sequenced to find out more.

"We think that the genes for photosynthesis originally evolved only once about three billion years ago. So all plants, algae and blue green bacteria can produce their own energy from light because they have acquired these genes for photosynthesis," Professor McFadden said.

Like prisoners in Alcatraz, the captive algae appear to have been nurtured by their enslavers and the precious sugars produced from photosynthesis became a vit
