Individuality, Evolution, and Dancing
Ricki Lewis | Jun 12, 2005 | 3 min read
What is the unit of evolution, the level of life upon which natural selection acts? A geneticist would say the gene; Charles Darwin saw it in the unique populations on the Galapagos. On Friday, Leticia Aviles, associate professor of zoology at the University of British Columbia, singled out the individual as dividing the cellular from the group level. ?But what an individual is depends on one's frame of reference,? she said, and the level at which natural selection acts remains an unresolved is
