    "abstract": "We present a simple model of adaptive radiations in evolution based on\nspecies competition. Competition is found to promote species divergence and\nbranching, and to dampen the net species production. In the model simulations,\nhigh taxonomic diversification and branching take place during the beginning of\nthe radiation. The results show striking similarities with empirical data and\nhighlight the mechanism of competition as an important driving factor for\naccelerated evolutionary transformation.",
