A new method reveals a complete timetree of primates, including over 450 species, after aggregating untimed and timed phylogenies. This comprehensive tree represents the most complete description of primate evolution to date, enabling further research in fields like biogeography and conservation.
Researchers use machine-compiled data to construct a microbial supertree, addressing the challenge of accessing and synthesizing scientific literature. The study demonstrates the potential of high-throughput machine extraction in tackling the vast amount of published science.
A new study has found that the ancestors of modern mammals did not quickly evolve and spread to fill empty niches following the mass extinctions of dinosaurs. Instead, diversification rates dropped and stayed low for 40 million years, with modern mammal orders emerging around 50-55 million years ago.
