1·These episodes of rapid evolution are separated by relatively long static spans during which a species may hardly change at all.

2·Telomere length tends to shorten with age, and shorter telomeres tend to be linked with shorter life spans.
端粒的长度与寿命的长短有关，染色体端粒越短，它所在的生命跨度也就越短。
3·This Mosaic spans a slice of space that is equal to about a third of the diameter of the full moon (10 arc minutes).
这些镶嵌的空间切片的跨度相当于一个满月直径的三分之一(10弧分)。
4·The study’s findings may also help explain the Flynn effect, which can’t be accounted for by evolution (the IQ gains occur over time spans too short for natural selection).
该研究发现还可能对解释不能归因为进化（对于自然选择来说，获得IQ的时间跨度太短）的弗林效应有所帮助。
5·The study's findings may also help explain the Flynn effect, which can't be accounted for by evolution (the IQ gains occur over time spans too short for natural selection).
该研究发现还可能对解释不能归因为进化（对于自然选择来说，获得IQ的时间跨度太短）的弗林效应有所帮助。
