Evolutionary models demonstrate rapid and adaptive diversification of Australo-Papuan pythons

Damien Esquerre, Ian Brennan, Stephen Donnellan & Scott Keogh
Lineages may diversify when they encounter available ecological niches. Adaptive divergence by ecological opportunity often appears to follow the invasion of a new environment with open ecological space. This evolutionary process is hypothesized to explain the explosive diversification of numerous Australian vertebrate groups following the collision of the Eurasian and Australian plates 25 million years ago. One of these groups is the pythons, which demonstrate their greatest phenotypic and ecological diversity in Australo-Papua (Australia and...
