Quote | Molecular evolution tracks macroevolutionary transitions in Cetacea McGowen et al Trends In Ecology and Evolution, Volume 29, Issue 6, June 2014, P. 336346
Abstract: Cetacea (whales, dolphins, and porpoises) is a model group for investigating the molecular signature of macroevolutionary transitions. Recent research has begun to reveal the molecular underpinnings of the remarkable anatomical and behavioral transformation in this clade. This shift from terrestrial to aquatic environments is arguably the best-understood major morphological transition in vertebrate evolution. The ancestral body plan and physiology were extensively modified and, in many cases, these crucial changes are recorded in cetacean genomes. Recent studies have highlighted cetaceans as central to understanding adaptive molecular convergence and pseudogene formation. Here, we review current research in cetacean molecular evolution and the potential of Cetacea as a model for the study of other macroevolutionary transitions from a genomic perspective. |
From the paper
Quote | Highlights
• Cetacea (whales, dolphins, and porpoises) is a model group for investigating the molecular signature of macroevolutionary transitions. • Recent research has documented the remarkable convergence between echolocating bats and odontocetes across six genes related to auditory physiology. • Cetaceans are a premier model of wholesale sensory evolution, in which anatomical changes related to sensory perception dovetail nicely with molecular evolutionary patterns, including the pseudogenization of some visual opsins, olfactory receptors, vomeronasal receptors, and taste receptors. • Modifications in myoglobin also show that the net surface charge of myoglobin in cetaceans correlates with depth of dive, and these changes have also occurred in other aquatic lineages, such as pinnipeds. |

Eukaryotes- you don't have a mechanism capable of producing eukaryotes.
You don't have a mechanism capable of producing the genetic toolkit required to control the development of body plans.
There isn't enough time in the universe for blind and mindless processes to A) find the "right" genes and B) alter them in specific ways
Wholesale sensory evolution is well beyond evolution by means of blind and mindless processes.
Also the article assumes and does not demonstrate, macroevolution. |
Why did I know Joke would shit his pants and run from the genetic evidence for cetacean macroevolution? |
Why does timmy think its ignorance is evidence for macroevolution?
My claim is YOUR POSITION doesn't have a mechanism. And the SCIENTIFIC EVIDENCE that YOU presented supports that claim.
1- Your side cannot account for eukaryotes.
2- Given single-celled eukaryotes your side cannot account for the genes that control the development of body plans
3- Speciation occurs absent of a change in the type of body plan
4- Your blind acceptance of those papers, while amusing, just further exposes your desperation
5- As YOU have said, science has advanced since the 80s- and guess what? It doesn't help you
The EVIDENCE is:
timmy wants to know about limits- mechanisms, timmy- as in there aren't any known mechanisms capable of producing eukaryotes given starting populations of archaea and prokaryotes.
Everything we know says that bacteria always give rise to bacteria. Sponges always give rise to sponges. Fish always give rise to fish. Fruit flies always give rise to fruit flies.
You don't have a mechanism capable of producing anything beyond limited descent with modification.
timmy Horton, scientifically illiterate asshole
So please try to make your case that I ran from the evidence
-------------- "Facts are Stupid"- Timothy Horton aka Occam's Afterbirth
"Genetic mutations aren't mistakes"-ID and Timothy Horton
Whales do not have tails. Water turns to ice via a molecular code- Acartia bogart, TARD
YEC is more coherent than materialism and it's bastard child, evolutionism
