Moreover, venom research has mostly neglected ancient animal groups in favor of focusing on venomous snakes and cone snails, which are both «young» animal groups that originated only recently in evolutionary timescales, approximately 50 million years ago. (sciencedaily.com)
However, previous adaptations happened at evolutionary timescales, roughly one degree Celsius temperature increase per million years. (sciencedaily.com)
They demonstrated that species showing faster rates of genetic differentiation between populations are more likely to produce greater numbers of species over long evolutionary timescales. (sciencedaily.com)
