But because both species feed on the same prey in similar environments, they may have developed nearly identical physical traits — a process known
as parallel evolution.
We
find parallel evolution across three scales: within individual patients, in different patients in our study, and in the global influenza population.
Our topic is «Scaling Obama: Applying the Lessons of 2008 to State and Local Campaigns» (which I did NOT steal from the PDF panel; it's a case
of parallel evolution), and seeing as both Scott and Judith saw the Obama outreach operation from the inside, it should be a fascinating discussion.
Parallel evolution occurs when two independent species evolve together at the same time in the same ecospace and acquire similar characteristics (extinct browsing - horses and extinct paleotheres).
A new comparison of the gut microbiomes of humans, chimps (our closest ancestor), bonobos and gorillas shows that the evolution of two of the major families of bacteria in these apes» guts
exactly parallels the evolution of their hosts.
«We found these cichlids to be strong evidence
for parallel evolution that — interestingly — took place via different routes.
Konstanz evolutionary biologists working with Prof. Axel Meyer have now
described parallel evolution of two closely related, but geographically isolated populations of cichlid fish in Nicaraguan crater lakes.
«The young and completely isolated crater lakes along the Central American Volcanic Arc in Nicaragua provide an ideal setting to
study parallel evolution.
«They've actually been able to dig down into the genome and find out a little bit more about
[parallel evolution],» says Tim Coulson, a population biologist at the University of Oxford in the United Kingdom.
Convergent evolution is similar to, but distinguishable from, the phenomena of evolutionary relay and
parallel evolution.
The new bonanza of dinosauromorph fossils reveals a repeating pattern of
parallel evolution, such as lengthening legs or having legs oriented directly under the body.
Shaw says the results suggest that general intelligence «has evolved independently in the avian lineage» and that
parallel evolution of general intelligence among animals «could be more widespread than we currently realize.»
«So much for predictability and
parallel evolution!»
One beautiful case of
parallel evolution is the double domestication of rice in Africa as well as Asia, which was followed by its double «de-domestication,» or reversion to a wild form, all within the roughly 10,000 years since hunter - gatherers became settled farmers.
So far replicate Earths are in short supply, but cases of
parallel evolution (the same trait evolving independently in related lineages) allow scientists to ask some of the same questions.
This suggests that conserved genetic modules may be involved in the development, or
parallel evolution, of ant traits.
The different forms of eye in, for example, vertebrates and mollusks are often cited as examples of
parallel evolution.
There are other classic examples of
parallel evolution, but those species had a recent common ancestor, whereas the rove beetles have been diverging for more than a hundred million years.
Other researchers have looked beyond changes in behavior or physical features for «
parallel evolution» in the genes, finding, for instance, that different insects alter the same DNA to help them feed on toxic plants.
We have uncovered instances where similar patterns have evolved independently (
parallel evolution) via changes at the same gene as well as via different loci.
Our current understanding of the genetic basis of melanin - phenotype associations allows for both convergent and
parallel evolution, but this understanding is still limited.
He puts forward four scenarios: it could be (1) mosaic evolution (not all parts evolved at the same rate), or (2)
parallel evolution (bipedality evolved more than once from closely related ancestors), or (3) convergent evolution (bipedality evolved quite independently, from quadrupedal ancestors), or (4) the australopithecines could be unrelated to human evolution at all.
We propose to approach this question from the perspective of convergent and
parallel evolution to clarify to what extent different species have evolved the same associations owing to a shared genetic basis and being subjected to similar selective pressures.
You can create a lesson on the biology of digestion (in a chapter we call «How to Turn a Big Mac into a Linebacker»), evolution (a discussion of Darwin's finches that
parallels the evolution of the game), and engineering design (how scientists and engineers think differently about the league's concussion problem and how that might affect the design of a better football helmet).
While this transition in perception of feral cats was underway, the rest of the world was approaching through a process of
parallel evolution a whole new approach to rabies control and coping with street dogs ---- which would in turn influence a transition in how feral cats are treated.
«Our MEGA-plate takes complex, often obscure, concepts in evolution, such as mutation selection, lineages,
parallel evolution and clonal interference, and provides a visual seeing - is - believing demonstration of these otherwise vague ideas.
The color palette and continuous metamorphosis of paint into ambiguous forms recalls Philip Guston's late paintings, which had
a parallel evolution.
Mitochondrial gene rearrangements confirm
the parallel evolution of the crab - like form.
