Vast genetic diversity in the human population further influences trait inheritance while environmental effects, such as diet and upbringing, further complicate matters.
另一个显而易见的例子是,人类种群有时也快速进化以应对疾病,如攻击神经系统的库鲁(kuru)病。
It is also clear that human populations have sometimes evolved rapidly in response to diseases such as kuru, which attacks the nervous system.
它在遗传上是古老的,而且含有对所有人类种群都有用的信息。
It is genetically old andcontains information that is of interest to all human populations.".
乔布凌写到:“这就是为什么Y染色体在人类种群研究中得到如此广泛的运用。
Jobling writes,“This is why the Ychromosome is so widely used in human population studies.
这些变化可能又会反过来损害生物圈的运作和人类种群。
These changes canin turn damage both the functioning of the biosphere and human populations.
大幅提高数据收集的数量和速度都为我们提供了独特的前所未有的可以检测到环境和人类种群变化的机会。
Massive increases in the volume and speed of data gathering are providing us with unique andunparalleled opportunities to detect changes in the environment and human populations.
当我们研究遗传多样性时,我们能看到不同人类种群之间没有完全断开联系。
When we look at genetic diversity,we can see there are no clean breaks between human populations.
作为国际倡议的一部分,这些人进行了测序,以表征自然发生在人类种群中的遗传变异。
These individuals were sequenced as part of an international initiative tocharacterize the genetic variation that naturally occurs in human populations.
一旦将(基因)修改引入了人类种群,遗传的变化将很难被消除,也不会仅仅局限在任何单一的社群或国家。
Once introduced into the human population, genetic alterations would be difficult to remove and would not remain within any single community or country.
如果这些巢穴远离人类种群,我们可以与它们共存,直到自然消亡,那这会是一个更加人道的选择。
If these nests are away from human populations, this is a more humane option and we could coexist with them until nature runs its course.
这些研究发现激励着这一研究小组到人类种群中去寻找相似的性状。
The findings prompted the team to look for similar traits in human populations.
