The methylcitric acid (MCA) pathway for oxidizing propionate via methylcitrate to pyruvate is present inMethylotenera,Methylophilus, “Ca. M. turicensis”, and the marine OM43, but absent in all “Ca. Methylopumilus” strains, suggesting it has been selectively lost in these organisms. All ...
45,46,56. The evolutionary modularity of the Primary Mainland clade followed this expected pattern, suggesting that a close developmental genetic integration of limbs is ancestral also toAnolis. The shift in evolutionary modularity in Greater Antillean...
Recent genetic research has identified the rare tropical shrub Amborella as being the living plant most closely related to the ancient ancestor of all the angiosperms. This small shrub, which has tiny yellow-white flowers and red fruit, is found only on New Caledonia, a group of islands in ...
(298.9 million to 272.3 million years ago); the early ancestry of these orders is obscure, however, and the earliest fossils closely resemble present-day forms. One line from the evolutionary radiation at the beginning of the Permian gave rise to a mecopteroid stock, and there is good ...
This is a challenging geometrical problem and requires that packaging interconnection densities must closely track the evolution of microprocessor interconnection densities. In connecting the die to the motherboard, the package must also ensure that the connections do not unduly inhibit the microprocessor ...
9.Paleontologists are always attempting to determine evolutionary relationships among organisms.⬛One widely accepted hypothesis is that echinoderms are closely related to vertebrates-the group of animals that includes fish, reptiles, and mammals.⬛Although adult echinoderms do not resemble vertebrates bio...
One widely accepted hypothesis is that echinoderms are closely related to vertebrates-the group of animals that includes fish, reptiles, and mammals. Although adult echinoderms do not resemble vertebrates biologists have based this conclusion on DNA comparisons and embryological evidence. In most non-...
___ tested his hypothesis that domesticated species had been selected for ___ by selectively breeding silver foxes; chose this animal because it is a societal animal and is related to the dog and had never been ___ before; designed a breeding program that explicitly selected for ___; indiv...
One important aspect of this study is to investigate how the relationship between various resources (via the patch network) can affect the emergence of social ties. If a patch network has a ring structure, then it implies that a resource in a particular patch is more closely related to those...
The evolution of these problem driven groups is more or less completely documented by the papers published as outcomes of their research. By analyzing groups of closely related papers, researchers could extract rich information about knowledge processes [1,2,3,4]. The potential to map scientific ...
