Re: The Guardian of Eugenics Present?
Natural selection is the gradual, nonrandom process by which biological traits become either more or less common in a population as a function of differential reproduction of their bearers. It is a key mechanism of evolution.
Variation exists within all populations of organisms. This occurs partly because random mutations cause changes in the genome of an individual organism, and these mutations can be passed to offspring. Throughout the individuals’ lives, their genomes interact with their environments to cause variations in traits. (The environment of a genome includes the molecular biology in the cell, other cells, other individuals, populations, species, as well as the abiotic environment.) Individuals with certain variants of the trait may survive and reproduce more than individuals with other varients.

On the other hand will we encounter a "wipeout" of our species due to fertilization non-existance?

DEMOGRAPHIC WINTER: DECLINE OF THE HUMAN FAMILY
(USA, 2007, 52')
One of the most ominous events of modern history is quietly unfolding. Social scientists and economists agree - we are headed toward a demographic winter which threatens to have catastrophic social and economic consequences. The effects will be severe and long lasting and are already becoming manifest in much of Europe.
A groundbreaking film, Demographic Winter: Decline of the Human Family, reveals in chilling soberness how societies with diminished family influence are now grimly seen as being in social and economic jeopardy.
Demographic Winter draws upon experts from all around the world - demographers, economists, sociologists, psychologists, civic and religious leaders, parliamentarians and diplomats. Together, they reveal the dangers facing society and the worlds economies, dangers far more imminent than global warming and at least as severe. These experts will discuss how:
The population bomb not only did not have the predicted consequences, but almost all of the developed countries of the world are now experiencing fertility rates far below replacement levels. Birthrates have fallen so low that even immigration cannot replace declining populations, and this migration is sapping strength from developing countries, the fertility rates for many of which are now falling at a faster pace than did those of the developed countries.
The economies of the world will continue to contract as the human capital spoken of by Nobel Prize winning economist Gary Becker, diminishes. The engines of commerce will be strained as the workers of today fail to replace themselves and are burdened by the responsibility to support an aging population.
