根据几位朋友的来信中,常有提及这一问题的,所以愿约略的谈一下,供大家参考. 性选择或称类择或称雌雄淘汰都可.关于这一个理论是达尔文所提供的.在他1871年出版的“人类原始与性选择”一书中谈之甚详,他以许多材料来阐述了这个理论(当然早在其物种原始里也谈到),这给以前不能解释的许多现象以有力的说明.如好多雄性动物具有鲜艳的美色和能发出嘹亮的声调等,这些性状从表面看来,似乎是不利于它们的生存的,因为颜色越鲜艳则越容易被它们的敌人发见,就越容易死亡;同样的嘹亮的声调也是如此,达尔文以性选择的理论唯物的说明了这个问题.这个理论指出了这些性状对动物是有利的,是在自然选择的作用以下性选择形式所发展起来的.
According to the letters from several friends, there is often a mention of this issue, so I would like to talk about it in a slightly different way for reference. Sexual or gender selection may be either male or female. Regarding this theory, Darwin provided In his book, The Primitive and Sexual Options of Mankind, published in 1871, there is a very detailed account of this theory by many sources (of course as early as in its species’s origin), which gave previously unexplained Many phenomena are strongly explained by the fact that many male animals have bright colors and bright tones, which appear to be detrimental to their survival because the more vivid the color, the easier it is for them This is also true of the same loud tone, as demonstrated by Darwin’s theoretical choice of sexual selection, which states that these traits are good for animals and are subordinate to the role of natural selection The choice of form developed.
