查询词典 macroevolution

In fact, no solid evidence exists that supports evolution -- that is, macroevolution.

事实上，没有任何确凿的证据支持进化论，即所谓宏观进化论。

Macroevolution is a scale of analysis of evolution in separated gene pools.

宏观进化是对各种分离的基因库进行演变分析的一个尺度。

Larger changes , such as when a new species is formed , are called macroevolution .

大一点的变化，如新物种形成，被称之为宏观进化。

Some biologists feel the mechanisms of macroevolution are different from those of microevolutionary change .

一些生物学家认为宏观进化的机制与微观变化有所不同。

An example of macroevolution is the appearance of feathers during the evolution of birds from theropod dinosaurs.

宏进化的一个例子是鸟类在从兽角亚目的恐龙进化期间羽毛的出现。

I have made some researches about human macroevolution and variation , and made some analysis on the relationship of natural and cultural characters of human , and made a physical measurement about modern Chinese .

我主要进行了有关人类的宏观进化和变异方面的研究，还对人的自然性和文化性之间的关系以及现代中国人群的体质特征进行了分析。

Thus, the distinction between micro- and macroevolution is not a fundamental one – the only difference between them is of time and scale.

因此，微进化与宏进化的区别不是一个根本性的区别；它们之间的区别只是在时间上和规模上。

Evolution can be divided into microevolution and macroevolution.

进化可分为微观及宏观两种形式。

However, it should be noted that time is not a necessary distinguishing factor – macroevolution can happen without gradual compounding of small changes; whole-genome duplication can result in macroevolution occurring over a single generation - especially in plants.

但是，应该指出的是，时间不是一个必要的区分因素，宏进化可以在没有微小变化的渐进复合的情况下发生；全基因组的复制会导致宏进化在一代之中发生，尤其是发生在植物上。

While details of macroevolution are continuously studied by the scientific community, the overall theory behind macroevolution (i.e. common descent) has been overwhelmingly consistent with empirical data.

虽然科学界正在不断地研究宏进化的细节，基于宏进化的总体理论已经压倒性地与经验数据相一致。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
