Unless smokers are consistently located near more hospitable warm - water vents , chemosynthesis can account for only a fraction of the vent faunas 除非冒烟喷口附近总是存在着更为适宜的温水喷口，否则化学合成只能为一小部分喷口动物群提供食物。
Machiavellian traits may not be equally beneficial to other lineages , however , or even to all primates , and so this notion alone is unsatisfying 然而，马基维利形质在其他动物群中也许并不同样有利，即使灵长类也未必均蒙其利，因此这个理论并不是个令人满意的解释。
Another difficulty is that similarly dense populations of large deep - sea animals have been found in the proximity of “ smokers ” ? vents where water emerges at temperatures up to 350 另一个难点是人们在水温高达350的“冒烟喷口”附近发现了同样高密度的大型深海动物群。
