He’s Ba-a-a-ck: Lamarck Puts Pressure on Darwin – and ID, Too?

June 3, 2005

To historians of evolutionary theory, Lamarck is a 19th-century loser. His hypothesis of “inheritance of acquired characteristics,” according to high school textbooks and common knowledge, was debunked by experiment, and overturned when Darwin proposed natural selection as a mechanism for evolution.

The Origin of Specious Ideas: Did Darwin Explain Speciation?

Darwin’s Finches: Researchers Tweak the Beak

September 3, 2004

Every once in awhile, a new angle on Darwin’s finches (an icon of evolution) appears in print.

Can Evolution Create Homologous Structures by Different Paths?

April 22, 2004

Rethinking the Geological Layers

March 5, 2004

One of the most formative ideas in Darwin’s intellectual journey was the concept of gradualism, the principle of “small agencies and their cumulative effects.” This idea became a dominant motif in his philosophy of life. Describing how the assumption of gradualism permeated his last book (on earthworms) shortly before his death, Janet Browne, in her […]

February 13, 2004

Humanists hope to have a new international holiday by 2009: Darwin Day. (Feb. 12 was Darwin’s birthday as well as Abe Lincoln’s, so it’s already set aside as a holiday in America, but promoters want this to be an international event.)
