T-3-Q25-Q27两派学者对突变基因的不同认识和态度 那篇的一句话求中文释义

autumn1015

Researchers studying how genes control animal behavior have had to deal with many uncertainties. In the first place, most behaviors are governed by more than one gene, and until recently geneticists had no method for identifying the multiple genes involved. In addition, even when a single gene is found to control a behavior, researchers in different fields do not necessarily agree that it is a “behavioral gene.” Neuroscientists, whose interest in genetic research is to understand the nervous system (which generates behavior), define the term broadly. But ethologists ― specialists in animal behavior― are interested in evolution, so they define the term narrowly. They insist that mutations in a behavioral gene must alter a specific normal behavior and not merely make the organism ill, so that the genetically induced behavioral change will provide variation that natural selection can act upon, possibly leading to the evolution of a new species. For example, in the fruit fly, researchers have identified the gene Shaker, mutations in which cause flies to shake violently under anesthesia. Since shaking is not healthy, ethologists do not consider Shaker a behavioral gene. In contrast, ethologists do consider the gene period (per), which controls the fruit fly’s circadian (24 hour) rhythm, a behavioral gene because files with mutated per genes are healthy, they simply have different rhythms.

各位NN，我想请问一下mark成red这句话的中文释义？我search了一下以前的帖子，翻译成“ ethologist认为习性基因的变异一定会改变特定的正常行为但是不会令机体生病”.....

但是我怎们觉得应该翻译成“ ethologist认为习性基因的变异一定会改变特定的正常行为而不仅仅会令机体生病”.....完全是南辕北辙呀！not merely....应该怎样解释？那位大NN帮忙解释一下？？

自己顶一下。大牛在那里？

就是不只是的意思啊，就是不仅仅会使生病还会...
有点搞

是不仅仅会的意思,因为生病后还会进一步变异,这就是进化了,然后病的现象会克服.
