Nie: Where is the point at which humans move from natural selection
to ethical selection, or from animal beings into human beings?
Genes, the unit of heredity that allows natural selection
to operate, weren't even defined until 1909 when Danish botanist Wilhelm Johannsen devised the term--decades after Darwin's death in 1882--and until that point it was difficult, perhaps impossible, to operationalize Darwin's theory.
For teachers interested in understanding their students' reasoning about natural selection
, we suggest that there are two fundamental problems that must be solved: (1) assessing contextual competence so that instruction can be planned accordingly and (2) having a tool that can be modified but retains inferences of validity.
Meanwhile at 42West, a high-powered entertainment public relations firm, a letter to the news media that identified Natural Selection
as handling the Preservation Hall documentary at South by Southwest is now being described - in conversations conditioned on anonymity to minimise conflict- as having been in error.
Even more bewildering is the authors' contention that Charles Darwin conflated common descent and natural selection
into a single idea.
He says that at the heart of the ID movement are two types of argument, both designed to question the thought that natural selection
scales up, from microevolution on a short time scale, to macroevolution on a large time scale.
Mendel (The founder of genetic science) demonstrated the sudden discontinous mutations that greatly reduced the role of Darwinian natural selection
in determining the course of evolution.
This biography concentrates on the crucial two decades in Darwin's life between his famous voyage and the 1859 publication of the first edition of On the Origin of Species by Means of Natural Selection
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).
Scott: Because intelligent-design backers are a quite varied lot, some of them are concerned because evolution is incompatible with a literal interpretation of the Bible, but others are more concerned about the theological consequences of evolution by natural selection
being among the means by which God brought the world of living things into being.
It is impossible to understand Hitler's monstrous views apart from his belief in natural selection
applied to races.
The outbreak was traced to Natural Selection
Foods, based in San Juan Bautista, and the company has voluntarily recalled products containing spinach.
