Here's an interesting piece about mutations.

Thanks for the Wiki link about mutation. I spent several hours going from topic to topic, and down various side alleys of terminology and background. Had to stop to let it soak in...

Both fire and grazing alter the terms of competition for sunlight, water, and soil nutrients between various plant species. Fire knocks back woody invaders, and grazing alters the balance between...

I've taken quite a bit of statistics, including stochastic processes, and I know what "random" means in that context, but what does it mean in reference to changes in the genome? Does it mean that...

I'm not sure I understand what you mean by "a genetic mutation...an extra efficient enzyme". Do you mean that this cow's genome includes a whole new gene (which other cows don't have) that is coded...

Is there nothing new under the sun? Here's a reprint of an 1896 paper by J. M. Baldwin: A New Factor in Evolution.


This guy seems to be one of Baldwin's intellectual descendents/disciples:...

This is getting really good, because it's making me think, and read, and question some things that I thought I understood. I love it.

I checked out Ridley and some of his reviewers. Here's an...

Yes, there is a lot of really interesting research and innovation going on in rangeland ecology these days. In the past, too many "environmentalists" had a shallow and dangerously naïve view of...

Generally speaking there is a lot of genetic heterogeneity in cattle, some people would say too much. In the commercial segment of the industry, there has been a lot of crossbreeding, but the...

This is SO COOL. Thank you both for responding in such careful and thoughtful detail. I have a more than passing interest in the subject, since I raise beef cattle breeding stock for a living, and...

Yes, tell me more.

I read something not long ago where biologists were asked what they thought the most exciting and significant advances were in genetics in the last five years. I may not get...
