How interspecies competition led to a 'bizarre' pattern in our own evolutionary tree
Competition between species played a major role in the rise and fall of hominins—and produced a "bizarre" evolutionary pattern for the Homo lineage—according to a new University of Cambridge study that revises the start ...

Amazon butterflies show how new species can evolve from hybridization
If evolution was originally depicted as a tree, with different species branching off as new blooms, then new research shows how the branches may actually be more entangled. In "Hybrid speciation driven by multilocus introgression ...
