In celebration of Darwin’s 198th birthday, there will be lots of events–talks, etc.–going on around the world next week. I’ll be doing my part, heading to the Rockies to talk at Western State College in Gunnison, Colorado. My talk is entitled, “The Descent of Man, From Darwin to DNA.” I’ll be speaking at 7 on Tuesday, February 13, in the Kebler Ballroom at the College Union Building. It’s free and open to the public.

Speaking of hobbits, the paperback edition of my human evolution book is just about to come out, and you can order it now on Amazon. And if you prefer the resounding thwack of hard covers, the hardback edition is still available. For information on the innards of the book, see this post from last year.

Could 2007 see some new hobbits? I certainly hope so.
In October 2004, a team of scientists announced they had found bones of a hominid from the Indonesian island of Flores. They came to the astonishing conclusion that the bones belonged to a new species, which they called Homo floresiensis, which stood only three feet tall, lived as recently as 12,000 years ago, had a chimp-sized brain, and could use stone tools to hunt.

The Intergovernmental Panel on Climate Change is about to release its newest edition of its report on global warming. In this AP report, one of the scientists who co-authored part of the IPCC study promises that it will contain much more than a smoking gun. It will contain “a batallion of intergalactic smoking missiles.”
The IPCC has been strengthening its conclusions about human responsibility for the rise in global temperatures for a few years now. One thing that apparently will set this new edition apart will be a section that looks at the impact global warming is having on nature–plants blooming earlier, species moving towards the poles, and so on.

The Bay checkerspot butterfly’s story is all too familiar. It was once a common sight in the San Francisco Bay area, but development and invasive plants have wiped out much of its grassland habitat.
Conservationists have tried to save the butterfly by saving the remaining patches where it survives. But thanks to global warming, that may not be good enough.
Climate scientists expect that the planet will become warmer in the next century if humans continue to produce greenhouse gases like carbon dioxide. The California Climate Change Center projects the state’s average temperature will rise 2.6 to 10.8 degrees Fahrenheit. Warming is also expected to cause bigger swings in rainfall.
