A reader sends me this oldie but goodie:
In “Can evolution make things less complicated? Scientists suggest cell origins involved a forward-and-backward process” Becky Ham for MSNBC.com explained (May 18, 2006 – a century ago in these times) that
… the data suggest that eukaryote cells with all their bells and whistles are probably as ancient as bacteria and archaea, and may have even appeared first, with bacteria and archaea appearing later as stripped-down versions of eukaryotes, according to David Penny, a molecular biologist at Massey University in New Zealand.
Penny, who worked on the research with Chuck Kurland of Sweden’s Lund University and Massey University’s L.J. Collins, acknowledged that the results might come as a surprise.
“We do think there is a tendency to look at evolution as progressive,” he said. “We prefer to think of evolution as backwards, sideways, and occasionally forward.”
Don’t try this stuff on a traffic cop, if you are in a collision. Like, where was your vehicle headed when the collision occured? … and all that.
