galapageium leaves emerged in Darwin's finches. It is possible that this form of tool-use may have existed for a long time and has gone unnoticed despite the fact that several research groups have studied the behaviour of Darwin's tree finches at the same study site for two decades. It ...

tracking the fates of the finches on the small, uninhabited island of Daphne Major. Their work has profoundly altered our understanding of how a group of eighteen species has diversified from a single ancestral species, demonstrating that evolution by natural...
In 1809, Charles Darwin’s year of birth, a French Naturalist, Jean-Baptiste Lamarck, theorized about the evolution of species on his work ofor. This concept stated that species would pass their acquired improved characters to their descendants and so, modify their nature throughout every generat...
Darwin demonstrated that these variations were closely linked to the way the finches found their food on the different islands. The ground finches with steeply profiled beaks lived on pine cone seeds, the little warbler finches lived on insects, and the tree finches lived on termites extracted ...
Evolutionarily derived forms are termedapomorphicforms, abbreviatedapomorphies.If several species (or higher taxa) within the studied phylogenetic line inherited certain apomorphies from their common ancestor, this apomorphy is termed a synapomorphy; in contrast anautapomorphyis an apomorphy that no ot...
(CC source: Wikimedia) With this argument, Darwin helped advance the field of evolutionary psychology and usher forth the robust scientific study of emotional experience. His basic thesis has been elaborated, refined, studied and debated ever since. ...
