Evolution is a process that results in changes in the genetic content of a population over time. There are two general classes of evolutionary change: microevolution and macroevolution.
Jun 3, 2024 · Evolution - Darwin, Natural Selection, Genetics: All human cultures have developed their own explanations for the origin of the world and of human beings and other creatures. Traditional Judaism and Christianity explain the origin of living beings and their adaptations to their environments—wings, gills, hands, flowers—as the handiwork of an omniscient God. The philosophers of ancient Greece had their own creation myths. Anaximander proposed that animals could be transformed from one ...
Apr 16, 2024 · Posted April 16, 2024. While you’ve probably heard of the Triassic, Jurassic, and Cretaceous periods by way of their most charismatic animals, the dinosaurs, other units of geologic time are less well known. The Siderian Period, for example, rarely makes headlines because it is, by definition, old news – 2.5-billion-year-old news.
Jun 12, 2024 · Biology - Evolution, Natural Selection, Adaptation: As knowledge of plant and animal forms accumulated during the 16th, 17th, and 18th centuries, a few biologists began to speculate about the ancestry of those organisms, though the prevailing view was that promulgated by Linnaeus—namely, the immutability of the species. Among the early speculations voiced during the 18th century, the British physician Erasmus Darwin (grandfather of Charles Darwin), concluded that species descend from ...
Evolution, the flagship journal of the Society for the Study of Evolution, publishes articles in evolutionary biology focused on evolutionary phenomena and processes at all levels of biological organisation.

Oct 14, 2022 · "The concept of evolution as a historical event was a hot topic among biologists and geologists prior to Darwin’s book because there was so much evidence accumulating, but I suspect biological ...
Evolution is the change in inherited traits that occurs in a group of organisms over multiple generations. Inherited traits are those that are passed from parents to offspring via genes. Evolution is made possible by genetic variation, or gene differences, in a population. Genetic variation causes organisms within a population to have a range ...
