Professor Ernst Mayr, the scientist renowned as the father of modern biology, will celebrate his 100th birthday tomorrow by leading a scathing attack on creationism.
The evolutionary biologist, who is already acclaimed as one of the most prolific researchers of all time, has no intention of retiring and is shortly to publish new research that dismantles the fashionable creationist doctrine of “intelligent design”.
Although he has reluctantly cut his workload since a serious bout of pneumonia 18 months ago, Prof. Mayr has remained an active scientist at Harvard University throughout his 90s. He has written five books since his 90th birthday and is researching five academic papers. One of these, scheduled to appear later this year, will examine how “intelligent design” — the latest way in which creationists have sought to present a divine origin of the world — was thoroughly refuted by Charles Darwin a century and a half ago.
His work is motivated in part by a sense of exasperation at the re-emergence of creationism in the USA, which he compares unfavourably with the widespread acceptance of evolution that he encountered while growing up in early 20th-century Germany.
The states of Florida, Mississippi, Missouri, Illinois, Kentucky and Oklahoma currently omit the word “evolution” from their curriculums. The Alabama state board of education has voted to include disclaimers in textbooks describing evolution as a theory. In Georgia, the word “evolution” was banned from the science curriculum after the state’s schools superintendent described it as a “controversial buzzword”.
Fierce protest, including criticism from Jimmy Carter, the former President, reversed this.
Prof. Mayr, who will celebrate his 100th birthday at his holiday home in New Hampshire with his two daughters, five grandchildren and 10 great-grandchildren, was born on 5 July 1905 in Kempten, Germany. He took a PhD in zoology at the University of Berlin, before travelling to New Guinea in 1928 to study its diverse bird life. On his return in 1930 he emigrated to the USA. His most famous work, Systematics and the Origin of Species, was published in 1942 and is regarded still as a canonical work of biology.
It effectively founded the modern discipline by combining Darwin’s theory of evolution by natural selection with Gregor Mendel’s genetics, showing how the two were compatible. Prof. Mayr redefined what scientists mean by a species, using interbreeding as a guide. If two varieties of duck or vole do not interbreed, they cannot be the same species.
Prof. Mayr has won all three of the awards sometimes termed the “triple crown” of biology — the Balzan Prize, the Crafoord Prize and the International Prize for Biology. Although he formally retired in 1975, he has been active as an Emeritus Professor ever since and has recently written extensively on the philosophy of biology.

Abstract:
Under what circumstances speciation in sexually reproducing animals can occur without geographical disjunction is still controversial. According to the ring-species model, a reproductive barrier may arise through 'isolation by distance' when peripheral populations of a species meet after expanding around some uninhabitable barrier. The classical example of this kind of speciation is the herring gull (Larus argentatus) complex, with a circumpolar distribution in the Northern Hemisphere. Based on mitochondrial DNA variation among 21 gull taxa, we show that members of this complex differentiated largely in allopatry following multiple vicariance and long-distance-colonization events, not primarily through isolation by distance. Reproductive isolation evolved more rapidly between some lineages than between others, irrespective of their genetic distance. Extant taxa are the result of divergent as well as reticulate evolution between two ancestral lineages originally separated in a North Atlantic refugium and a continental Eurasian refugium, respectively. Continental birds expanded along the entire north Eurasian coast and via Beringia into North America. Contrary to the ring-species model, we find no genetic evidence for a closure of the circumpolar ring through colonization of Europe by North American herring gulls. However, closure of the ring in the opposite direction may be imminent, with lesser black-backed gulls about to colonize North America.
Yes, I read it and the title is quite correct. Frogs don't have glass asses.
Dead thread placemarker.
RIP.
What a weird question. Belief and proof are two quite different phenomena, hence one need not prove -- much less prove 'scientifically' -- an afterlife to be credulous of it.
