The ritual causes the lizard acting as the female to ovulate and lay her eggs.
這種儀式會(huì)引起扮演雌性角色的蜥蜴排卵并產(chǎn)卵。
Then, a few weeks later, the two lizards switch roles and repeat this process so that the second female will be able to ovulate and lay her eggs.
然后過(guò)幾個(gè)星期，兩只蜥蜴再交換角色，重復(fù)這種交配儀式，這樣另一只雌蜥蜴就可以排卵，產(chǎn)卵了。
That is strange.
太奇怪了。
And it raises a lot of interesting questions.
這也引發(fā)了許多有趣的問(wèn)題。
For example, it's not clear how well an all-female species can evolve and adapt to environmental changes.
例如，對(duì)于這種全雌物種如何更好地進(jìn)化以適應(yīng)環(huán)境變化目前還不清楚。
A species' survival depends in part on variation among its members.
一個(gè)物種的生存要部分依靠成員的變異。
If all the members of a species are identical,chances are greater that something like a change in the climate or a disease will wipe them all out.
如果所有的成員基因都一模一樣，那么一遇到氣候變化或者災(zāi)害，她們?nèi)姼矝]的機(jī)會(huì)就很大。
So it might be a little early to do away with males.
所以排除雄性還為之過(guò)早。
Well, you know what they say. You can't live with them.
嗯，你知道她們是怎么說(shuō)的。你沒辦法和他們一起生活。
You can't live without them.
但你的生活不能沒有他們。
