n.
Large-scale evolution occurring over a very long period time that results in the formation of new species and higher-level taxonomic groups.

mac′ro·ev′o·lu′tion·ar′y (-shə-nĕr′ē) adj.

macroevolution

A term of art for large-scale evolution of ecologically separated gene pools, which occurs at or above the level of speciation, resulting in relatively large and complex changes such as anagenesis and cladogenesis stasigenesis.

macroevolution

the collective processes by which new species arise and others become extinct.

Consequently, future studies that (1) obtain data from multiple molecular markers for a broad cross-section of beetles, neuropterids and Strepsiptera, (2) incorporate the latest information from the beetle fossil record, and (3) use appropriate and statistically rigorous methods for estimating beetle phylogeny and divergence times will undoubtedly contribute further and more robust insights into beetle phylogeny and macroevolution, including factors contributing to the apparent success of the order.
If Christians would merely insist that all examples used to support evolution be clearly identified as micro- or macroevolution, the fraud would soon be exposed.
But only the theory of punctuated equilibrium, Gould argued, could predict exactly what we have found (and not found) in the fossil record--evidence of overwhelming changelessness and sudden morphological macroevolution among small and geographically peripheral populations.
From noticeably broad gaps in the fossil record (which Darwin himself commented on) to questions of extreme improbability with regard to genetic mutations (nearly all mutations are harmful, and most others are useless--a strike against the idea that drastic evolutionary changes could be brought about by mutations), Reclaiming Science From Darwinism dares to present the case against macroevolution on purely scientific grounds, not theological or spiritual grounds.
The appendices clarify insights into a variety of topics, from the possible use of the Celtic Cross as a navigational tool to a thorough chastisement of the Darwinian theory of macroevolution (while acknowledging that microevolution, as seen through small species changes due to simple natural selection, does exist).
Benedict's affirmation of microevolution while denying macroevolution to escape materialist philosophy won't work (NCR Sept.
17) This would be expected as the likelihood of such a large scale mutation being beneficial is very slim, but the end result, if successful, is macroevolution within one generation.
I recently found in these pages an interview with Durston, in which he essentially says that most evolutionary biologists work under profound ignorance regarding information theory, and this ignorance is the only thing that allows these unsophisticated researchers to conclude merely from bones and teeth that macroevolution ever occurred.
We examined macroevolution of defense traits in 24 species of milkweeds (Asclepias).
In the first four chapters of the book he tests whether evidence for macroevolution is convincing.
