Unanimous agreement is still theoretically ideal, especially in cases when you'd expect very low odds of variability and uncertainty.

一致同意仍然是理论上的理想，尤其是那些你预期变异性不确定性机率很低的案例。

There's just so much variability in cats, as I mentioned.

正如我提到的，猫的变异性如此之大。

This greater variability in mongrels than in hybrids does not seem at all surprising.

杂种杂种更大的变异性似乎并不令人惊讶。

The variability, however, in the successive generations of mongrels is, perhaps, greater than in hybrids.

然而，连续几代杂种的变异性杂交种更大。

Users wear it on their arm. The device has a sensor that measures hemoglobin oxygen levels and changes to the heart rate called HRV.

用户需要将它戴在手臂上。该设备附带的传感器测量血蛋白氧水平心率变异性（HRV）。

Chinese researchers have found that greenhouse warming and internal variability have increased the frequency of extreme El Nino and Central Pacific El Nino events since 1980.

中国研究人员发现，自 1980 年以来，温室效应变异性增加了极端厄尔尼诺中太平洋厄尔尼诺事件的频率。

Physiological benefits such as our heart variability, which is a predictor of longevity, which is a predictor of health is increased. The parasympathetic system increases when we are grateful.

对身体的好处，包括心率变异性，它预测我们是否长寿，预测我们是否健康。当我们感激时，副交感神经系统功增强。

Variability is not actually caused by man; he only unintentionally exposes organic beings to new conditions of life and then nature acts on the organisation and causes it to vary.

变异性实际上并不是人为造成的；他只是无意中将有机生物暴露在新的生活条件下， 然后自然对组织起作用并使其发生变化。

Some have even imagined that natural selection induces variability, whereas it implies only the preservation of such variations as arise and are beneficial to the being under its conditions of life.

有些人甚至想象自然选择会引起变异性，而它意味着只保存出现的变异， 这些变异对生物在其生活条件下是有益的。

We can, for instance, plant a seed, and we can not only have a look at how it grows as time goes by, but we can also influence the grow variability and shoot growth rates.

举个例子，我们以种一粒种子，然后我们不仅以看到它随着时间如何生长，还去影响它生长的变异性改变它的生长率。

Under domestication we see much variability, caused, or at least excited, by changed conditions of life; but often in so obscure a manner, that we are tempted to consider the variations as spontaneous.

在驯化过程中， 我们看到了由改变的生活条件引起或至少激发的许多变异性；但往往以一种如此晦涩的方式， 以至于我们很容易将这些变化视为自发的。

It is only in those cases in which the modification has been comparatively recent and extraordinarily great that we ought to find the generative variability, as it may be called, still present in a high degree.

只有在那些修改相对较新且非常大的情况下， 我们才应该发现生成变异性， 正如它被称为的那样， 仍然在很大程度上存在。

Variability in the same parts of the organisation has generally been taken advantage of in giving secondary sexual differences to the two sexes of the same species, and specific differences to the several species of the same genus.

通常利用组织相同分的变异性来赋予同一物种的两种性别以次要性别差异，以及同一属的几个物种的具体差异。

I will then pass on to the variability of species in a state of nature; but I shall, unfortunately, be compelled to treat this subject far too briefly, as it can be treated properly only by giving long catalogues of facts.

然后我将继续讨论自然状态下物种的变异性；但不幸的是， 我将不得不过于简短地处理这个主题， 因为只有给出长长的事实目录才恰当地处理它。
