plants and animals. The common notion is that miRNAs have evolved independently in those distinct lineages, but recent evidence from non-bilaterian metazoans, plants, and various algae raise the possibility that the last common ancestor of these lineages might already have employed an miRNA pathway ...
The fungi, plants, and animals are thought to have evolved from different groups of protists. Plants are multicellular organisms that have evolved the ability to live on land. The vast majority can carry out photosynthesis, but they are not the only organisms with this ability: many protists...

Virtually all plants and animals, including humans, are home to symbiotic microorganisms. Symbiotic interactions can be neutral, harmful or have beneficial effects on the host organism. However, growing evidence suggests that microbial symbionts can evolve rapidly, resulting in drastic transitions along ...

and all plants and animals derive from bacteria-like microorganisms that originated more than 3 billion years ago. Biological evolution is a process of descent with modification. Lineages of organisms change through generations; diversity arises because the lineages that descend from common ancestors dive...
the evolution of plants and animals also show climatically-sensitive evolutionary trends that are well characterised in hominids, Bovidae, birds and plants63. Although the mechanisms may be different in different realms, the evolutionary pulsed turnover of new species63may generally be associated with...
