In modern biology, natural selection is a process whereby species which have traits that enable them to adapt in an environment survive and reproduce, and then pass on their genes to the next generation. Natural selection means that species that can adapt to a specific environment will grow in ...

Fitness and natural selection were first explained in detail by Charles Darwin, who observed wildlife around the world, took copious notes, then sought to understand what he had seen. Natural selection is probably best explained in his words, taken from his landmark work "On the Origin of Spec...

'Natural selection' is, it seems, an ambiguous term. It is sometimes held to denote a consequence of variation, heredity, and environment, while at other times as denoting a force that creates adaptations. I argue that the latter, the force interpretation, is a redundant notion of natural ...
Natural selection is the process by which one type of animal within a species ___ because of certain characteristics that make it more likely to live than others in its group. The history of the peppered moth(灰蛾)is an example of the natural selection process. In 19th century England, ...
Natural selection is a mechanism for generating an exceedingly high degree of improbability. 自然选择就是能生成极不可能之事的机制。 ——Ronald Fisher(费舍) 从生物学里找计算的模型,一直是人工智能的研究方向之一,学术上大致有两条传承的脉络:一条源自麦卡洛克和皮茨的神经网络,演化到今天成了深度学习;另一...
