By virtue of the high similarity between their seed regions, often resulting from common evolutionary ancestry, miRNA families are thought to consist of miRNAs with similar biological function, and to a certain extent redundantly targeting the same mRNAs31,39.
Another is the herringbone pattern, believed to result from an evolutionary concrescence (growing together) of pinnae, as shown by certain tree ferns (Cyathea), lady ferns (Athyrium), and marsh ferns (Thelypteris).
An evolutionary ontology of the living world should distinguish the real evolutionary players, the units with causal powers resulting from or contributing to evolutionary processes.
Of course, turtles live vastly different lives than birds do, so turtle toothlessness could potentially result from different evolutionary pressures than those faced by birds.
The subsequent red nodes may result from independent evolutionary innovation or horizontal gene transfer.
I should think some of the findings might result from evolutionary pressures -- particularly the survival value of certain skills at certain ages.
Distantly related protein families can result from gene duplication events followed by sequence and functional divergence, or from accelerated evolution in certain evolutionary lineages.
They follow rules that result from evolutionary forces and function kind of like an artificial intelligence program.
Seven major conodont lineages went extinct, but were replaced by nine new lineages that resulted from a major evolutionary radiation.
However, we suspected that gene loss was not random and resulted from a converging evolutionary process.
We believe this topology consistency resulted from the large evolutionary distances among the organisms we analyzed.
