达尔文主义与优生学

Darwinian fitness───达尔文适合度；达尔文氏适合度

Darwinian theories───达尔文学说，达尔文进化论

accident and emergencies───急诊室

gin and tonics───琴酒补剂；杜松子酒补剂

Whenever biology meets behaviour the spectre of social Darwinism and eugenics looms menacingly in the background.───无论何时用生物学解释行为，社会达尔文主义和优生学的幽灵就会在这种背景下浮出水面。

But this time, instead of being explicitly linked to theories like eugenics and social Darwinism, it was propelled by the emerging ideology of environmentalism.───但这次的公众讨论不再与优生学或社会达尔文主义有关，推动这些讨论的是新兴的环保主义理念。

In the early twentieth century, Malthusian ideas on population control were linked to theories of eugenics and social Darwinism.───在二十世纪早期，马尔萨斯对于人口控制的想法还与优生学和社会达尔文主义有关。
