The Plant Food Tree of Life leads you through the major plant foods and their evolutionary relationships. It is a complement to the list view of the same information, in which each link takes you to a related article at the excellent blog, The Botanist in the Kitchen.
Collective violence, extending from riots to warfare, presents a challenge to our ordinary understanding of free will. Actions that would rarely be taken by an individual on their own seem to be embraced when supported by a larger group. This can occur in societies ranging from the communist regime of Soviet Russia to the capitalist free market of modern day England. Given this commonality, perhaps the collective violence of a riot can be best understood as a biological event in which evolved cognitive responses encounter a unique environmental threat. And if that is the case, do individuals caught up in such incidents have any choice in the matter?Freedom to Riot: an evolutionary perspective on collective violence.
Indeed, at 6 million years of separation, the difference in [Y-chromosome] gene content in chimpanzee and human is more comparable to the difference in autosomal gene content in chicken and human, at 310 million years of separation.It is commonly said that the Human and Chimpanzee genomes share 99% or more identical DNA. In a surprising development about to be published in Nature, the Y-chromosomes of these two species were found to share only 70% of their DNA, raising important questions about the mode and tempo by which speciation from a common ancestor occurred. This finding may point the finger at the evolution of different patterns of sperm-competition and mating practices within these two species.
