Genetic Changes In Mice 'Question Evolution Speed'

Genetic changes in mice 'question evolution speed'
A species of mouse has evolved dramatically in just 150 years, showing genetic change can occur much faster than was thought possible.
The discovery was made by accident by two American biologists studying the genetic make-up of a common wild mouse in Chicago.
Dr Dennis Nyberg and Dr Oliver Pergams, both from the University of Illinois at Chicago, analysed DNA samples from 56 museum specimens of the white-footed mouse dating back to 1855, and 52 wild mice captured from local forests and parks.
They found startling genetic differences between the 19th century and modern mice.
Only one of the present-day mice had DNA that matched that of mice collected before 1950.
While fast evolutionary change has been seen in fruit flies, such rapid evolution in a mammal has not been reported before.
The scientists, whose findings appear in the journal Nature, believe humans may have been partly responsible for the "new" mice.
"Settlers may have brought in mice with the favourable gene that were able to out-compete mice with the native variant," said Dr Pergams.

Dude, half of those guys lived before Darwin was even born.

How can a person be a "Darwinist" if he or she died before Darwin was even born?

Breaking you own rules it seems.
Since I never said they were "Darwinists", you purposely took me out of context.

Patrick's about due for a placemarker.
This one's on the house.
To: ALS
and all this time we were doubters... The profundity in that illustration is not that a well-dressed ape evolved into a man, but that the entire process is represented with a small gray arrow.
To: ALS
Okay, since Darwin originated the Theory of Evolution, how can anyone who died before Darwin was born be an evolutionist? That would be like me saying that Isaac Newton did not subscribe to Einsteinian physics as evidence that the latter was wrong.

OK dummy. Let me make this super dooper simple for ya.
Read the title above the names. Does it say "Darwinists"?
earth to Junior Samples.
meanwhile, munch on this here
