Researchers reveal that, under certain circumstances, the process of evolution can be highly predictable, especially when there are limited solutions to a particular problem, such as resistance to dangerous toxins

A research paper that was published a few days ago in the journal, Proceedings of the National Academy of Sciences, reports that evolution can follow predictable pathways when available solutions to a particular problem are severely limited. This new study found that resistance to heart-stopping cardiac glycoside toxins produced by some plants and animals for defensive purposes has independently converged across several lineages of insects, amphibians, reptiles, and mammals, after following a highly predictable evolutionary pathway.
