Ultimately, Grasso hopes the work will lead to plume-tracking systems that exceed even the lobster's innate abilities: "If we move toward the lobster's solutions, then along the way we may discover a turn that the lobster was evolutionarily
unable to take, that we could exploit and use to develop even better systems.
Although at first blush these features seem to suggest that Bunostegos was an evolutionarily
advanced pareiasaur, it also had many primitive characteristics.
But having extra copies doesn't mean the gene is evolutionarily
RNA silencing was first noticed in plants when attempts to create transgenic plants that overexpressed a natural gene often had the opposite effect; later it was found to be an evolutionarily
conserved defense mechanism against plant RNA viruses and other molecular parasites.
More recently described dinosaur fossils such as Microraptor gui (illustrated above) have featured more evolutionarily
complex feathers with central shafts.
Jorgensen had serendipitously discovered an age-old natural biologic process now recognized to be evolutionarily
conserved in most, if not all, forms of life.
The coelacanth is critical to study because it is one of only two living lobe-finned fish groups that represent deep and evolutionarily
informative lineages with respect to the land vertebrates.
In a charming paean to plants sometimes ignored and often detested, nature writer Mabey points out that weeds are evolutionarily
primed for success: They tend to grow quickly and produce prodigious numbers of seeds.

close, larger relations.
Instead, as Switek illustrates through captivating timelines of discoveries, scientists found a much more haphazard process, resulting in a melange of "primitive" forms living alongside their evolutionarily
