Evolution of Diversity of Life on Earth (03:20)
Professor Allan Wilson of the University of California, Berkeley, gave science new ways to understand how the diversity of life on earth evolved.
Early Years of Allan Wilson (03:35)
Born and raised on a New Zealand farm, young Allan Wilson showed an intelligent interest in evolution. He attended Kings College and performed well scholastically and athletically. Biology teachers did not broach the subject of evolution.
Allan Wilson's Education in New Zealand and America (03:54)
Wilson studied biochemistry at the university level, planning to combine farming and scientific techniques. He pursued his interest in studying birds. Wilson comes to the U.S. to study biochemistry, and completes his doctoral work at Berkeley.
Theory of Evolution: Molecular Clock (02:50)
On the faculty at the UC Berkeley campus, Wilson continues to quantitatively study the evolution of birds. He discovered that the relationship between time and genetic change cast a new light on evolution.
Study of Paleoanthropology (04:32)
Studying human evolution and chimp evolution, Allan Wilson argues that earlier theories that homo sapiens evolved from Ramipithecus was in error. At issue scientifically was how scientists should measure the relationships between close prehistoric relatives.
Similarities Between Humans and Chimpanzees (02:38)
If the molecules of humans and chimps are so similar, why do the two species look so different? Allan Wilson and a colleague attempted to answer this is a paper that was featured in "Science" in 1975.
Scientific Value of Mitochondrial DNA: Search for Eve (05:21)
Mitochondrial DNA allows scientists to look at genealogy in a direct line through the females. The study of 150 samples from all over the world suggested a common female ancestor in Africa that lived 150,000 years ago.
Revolutionary Ideas About Human Evolution (01:35)
As scientific studies of the evolution of man get closer to the social sciences, the more difficult it is to change long-held beliefs. Many people reject the idea that biochemistry could reveal so many secrets of human evolution.
DNA Sequence Multiplication (03:35)
Polymerase chain reaction (PCR) enables researchers to produce millions of copies of a specific DNA sequence in approximately two hours. This automated process bypasses the need to use bacteria for amplifying DNA.
Study of Ancient DNA (04:33)
The PCR method allows scientists to study ancient DNA. Allan Wilson studies the evolution of the extinct Moa bird. This method tells how environmental changes contributed to evolutionary changes in the absence of humans.
Legacy of Allan Wilson: Gene Studies (03:18)
Allan Wilson receives many honors for his work in evolutionary DNA. One of his students, now of Celera Diagnostics, studies the links between the genes humans carry and the diseases humans get.
