Along with the orders Laurales, Magnoliales, and Canellales, Piperales forms the magnoliid clade, which is an early evolutionary branch in the angiosperm tree; the clade corresponds to part of the subclass Magnoliidae under the old Cronquist botanical classification system.
But the past decade or two of research, which is marked by the discovery of thousands of specimens of early birds and flying dinosaurs, also shows that feathers were an early evolutionary innovation even if they probably arose for reasons unrelated to powered flight, such as insulation or sexual display.
Instead, there is an early evolutionary origin for such preferences and biases, and these traits evolved in a common ancestor to monkeys, apes and humans and was then passed down through the generations.
An analysis of UCP homologue evolution by Sokolova and Sokolov [28] starting with the invertebrate UCP isoforms suggests that the divergence of UCPs is an early evolutionary event, which explains the functional diversity of this protein family in vertebrates and mammals.
The Osiris gene family was an early evolutionary innovation in the divergence and spread of insects.
They are probably an early evolutionary side branch that gave rise to no other group of animals.
Consecutive repression of HR in Oenothera seemed to be restricted in an early evolutionary stage in bivalent formers and is likely to be a pre-requisite for the evolution of reciprocal translocations and superlinkage groups, because it ensured perpetuation of their advantages.
In addition, the ubiquitous PHGPx genes with different biochemical properties are likely to have been separated in an early evolutionary time.
I felt then that music hits us in a deeper place than speech and must be an earlier part of our evolutionary history.
The fact that Anomalocaris had such keen eyesight may have been part of an early evolutionary arms race, the authors suggest.
