Answer:
A new field known as <u>nutrigenomics</u> has emerged to explore the epigenetic influences of diet.
Is there a picture to go with this?
There is only one measure of "evolutionary success": having more offspring. A "useful" trait gets conserved and propagated by the simple virtue of there being more next-generation individuals carrying it and particular genetic feature "encoding" it. That's all there is to it.
One can view this as genes "wishing" to create phenotypic features that would propagate them (as in "Selfish Gene"), or as competition between individuals, or groups, or populations. But those are all metaphors making it easier to understand the same underlying phenomenon: random change and environmental pressure which makes the carrier more or less successful at reproduction.
You will sometimes hear the term "evolutionary successful species" applied to one that spread out of its original niche, or "evolutionary successful adaptation" for one that spread quickly through population (like us or our lactase persistence mutation), but, again, that's the same thing.
Answer:
Mississippian fossils are abundant in portions of the Midwest and South and include vast beds of limestone and marble.
Explanation:
For example, the domed ceiling of the Jefferson Memorial in Washington, D.C., is made of Indiana limestone that was deposited during the Mississippian Period.By the end of the Carboniferous, reptiles had migrated well toward the interior of Pangea. These early pioneers went on to spawn the archosaurs, pelycosaurs, and therapsids of the ensuing Permian period. (It was the archosaurs that went on to spawn the first dinosaurs nearly a hundred million years later.)
