Evolution has been the foundation and guiding theory of biology since Darwin gave the theory its proper scientific debut in 1859. But Darwin probably never dreamed that researchers in 2005 would still be uncovering new details about the nuts and bolts of his theory -- how does evolution actually work in the world of influenza genes and chimpanzee genes and stickleback fish armor? Studies that follow evolution in action claim top honors as the Breakthrough of the Year, named by Science and its publisher AAAS, the nonprofit science society.
In 2005, scientists piled up new insights about evolution at the genetic level and the birth of species, including information that could help us lead healthier lives in the future. Ironically, these often-startling discoveries occurred in a year when backers of "intelligent design" and other opponents of evolution sought to renew challenges to this fundamental concept.
This milestone, plus nine other research advances, make up Science's list of the top ten scientific developments in 2005, chosen for their profound implications for society and the advancement of science. Science's Top Ten list appears in the 23 December 2005 issue of the journal Science.
Many of this year's breakthrough studies followed evolution at the genetic level. In October this year, an international team of researchers unveiled a map of the chimpanzee genome. Scientists are already poring over the chimpanzee genome and another international effort, the biggest map to date of single-letter variations in the human genetic s
