The tree of life is a metaphor used to describe the evolutionary relationships between all living organisms. It is represented as a branching diagram, with different branches representing different groups of organisms that share a common ancestor.
These microbial predators are divided into two groups, one of which has been referred to as “nibblerids” due to their use of tooth-like structures to bite off pieces of their prey. The other group, known as “nebulids,” consume their prey whole. Both groups form a distinct ancient branch called “Provora,” according to a recent study published in the journalLike lions, cheetahs, and more familiar predators, these microbes are numerically rare but important to the ecosystem, says senior author Dr.
Understanding more about these potentially undiscovered branches of life helps us understand the foundations of the living world and just how evolution works.
