Sentence examples for modified by natural from inspiring English sources

The structure of soil is also dynamic and modified by natural factors and management intervention.

The present level of understanding the mechanism of the enantioselective hydrogenation of α-ketoesters over platinum, chirally modified by natural cinchona alkaloids is reviewed with special emphasis on the enantioselective hydrogenations of ethyl and methylpyruvate to the corresponding lactates.

These examples indicate that in semelparous forms, in which full vigour and function are required until virtually the end of life, senescence has an onset closely coupled with the completion of the reproductive process and is governed by relatively simple enzymatic mechanisms that can be modified by natural selection.

One important feature of modularity for eye evolution is that the genes, biochemical pathways, and even the final assembly of components can be modified by natural selection individually or collectively (Franz-Odendaal and Hall 2006; Oakley 2003).

At first, the combined structure (B) may perform the new function rather poorly, but if it nonetheless confers some advantage over alternatives lacking the structure, then the components may be modified by natural selection favoring improvements in this new function (C).

Rather than "bricolage," the term "collage" may more effectively encapsulate this concept.3 Because a new function emerges through the combination of existing components, and especially once further modified by natural selection for this new function, a feature produced through "collage" becomes much more than the sum of its parts.

Because many pigments are formed as the natural or only slightly modified by-products of metabolic processes, some coloration may be without adaptive function.

A deficit in the analogy between neural networks and ecosystems is that whereas neural networks acquire the organisation necessary for their collective behaviours through learning mechanisms designed for that purpose, ecological connections are modified by individual-level natural selection with no such system-level purposes in mind.
