The stick insects may indeed have evolved a new set of wings, but it is not clear whether this change appeared as reverse evolution at the molecular level.
竹节虫确实是重新长出了翅膀，但是还并不清楚在分子水平上这是不是逆演化。
In 1994, Rudolf Raff and colleagues at Indiana University in the USA decided to use genetics to put a number on the probability of evolution going into reverse.
1994年，美国印第安纳大学的鲁道夫·拉夫和他的同事们决定用遗传学的方法来计算进化发生逆转的概率。
It is, wrote Kenneth Weiss of the Los Angeles Times in 2006, as if "evolution is running in reverse".
肯尼斯•外斯2006年在《洛杉矶时报》上写到，这好像是“进化在朝相反的方向进行”。
Examining the evolution of one protein, a team of scientists declares the answer is no, saying new mutations make it practically impossible for evolution to reverse direction.
通过研究一种蛋白质的进化历程，一个科研小组声明：答案是不行！新的突变是不可能使进化朝向逆转方向的。
The selection differential on a phenotypic trait was a necessary condition for fish to cause evolution, and also the evolutionary change caused by fishing were likely to be hard to reverse.
目前，导致这些变化的原因还不是很清楚，但捕捞选择性很可能是造成鱼类表形性状变化的主要原因。
