aHis conception of the struggle for life and of the natural selection of characteristics, so widely adopted by the thinkers of his day, popularized the principles of Lamarck as to the casual formation of new characteristics in a species by adaptation to environment; Darwin's conception carried th...
aThis difficult case illustrates the power of natural selection in selecting characteristics that could have been acquired only through variation and not through habit. 这个困难的案件在选择可能仅获取了通过变异和不通过习性的特征说明自然选择的力量。[translate]...
Sexual dimorphism in the tusked frog, Adelotus brevis (Anura:Myobatrachidae): the roles of natural and sexual selection At least two adaptive processes can lead to the evolution of sexual dimorphism: sexual selection (e.g. male-male combat) or natural selection (e.g. dietary... Kaliope,Kat...
(融合)into their surroundings. During that time period, great changes were happening in Great Britain. The Industrial Revolution was part of this change, and with it came air pollution. Natural selection often takes hundred or even thousands of years to occur. For the peppered moth, this ...
Natural selection on prefloration intervals may therefore vary in contrasting snowmelt environments and could influence the outcome of phenological responses to ... KA Stinson - 《American Journal of Botany》 被引量: 203发表: 2004年 PHOTOSYNTHETIC CHARACTERISTICS OF AN AMPHIBIOUS PLANT, ELEOCHARIS-VIVI...
After long-term natural selection, the integrated virus gradually becomes part of the human genome in a process called 'endogenization'. These account for approximately 8% of our genome[13]. In a study focused on two ECs, endogenization was believed to be the cause of viremia control and ...

On the other hand, in their natural habitat, there are some large carnivores like lions and leopards (Panthera pardus). Wild cheetahs tend not to visit the sites where such carnivores’ scent-mark is present31, suggesting that they might confine their marking to specific sites devoid of other...
In addition to the organic-rich shale in the Chang 7 Member (Ch7 shale) of the Ordos Basin, the shale hosted in the Chang 9 Member (Ch9 shale) is another source rock and potential unconventional target. However, there is a general lack of consensus on the features and potential of the...
