D. People plant different types of flowers in a garden. 相关知识点: 试题来源: 解析 C。解析:自然选择是指生物在生存斗争中适者生存、不适者被淘汰的现象。C 选项中昆虫对杀虫剂产生抗性是因为在使用杀虫剂的环境中,具有抗药性的昆虫能够生存下来并繁殖后代,这是自然选择的一个例子。A 选项是人工选择;B...
Natural selection is the process by which individuals with favorable traits are more likely to survive and reproduce, passing on those traits to future generations. An example of natural selection is the peppered moth, where the darker moths were more likely to survive and reproduce during the ind...

This process of retroelement capture of a non-retrovirus material has been experimentally demonstrated in a mammalian system37, but we are aware of only one previous natural example38, and in that case only the terminal repeats of the implicated element remained. The LTR retrotransposon we identify...
, Goldberg, 1989), and refer to it herein as the Induced Natural Selection Heuristic (INSH). By independently sampling new designs around each accepted design, we aim to avoid the pitfalls associated with some other optimisation routines. For example, INSH is able to sample multiple regions ...
