What we see today is the product of evolutionary events, resulting from the dispersal of a few human populations out of Africa around 60,000 to 70,000 years ago.

我们今天看到的是进化的产物，这是因为部分人在6-7万年前分散并离开了非洲。

The evidence is clearly starting to suggest that there were multiple migrations and dispersals in different parts of the world going in all kinds of directions and generally mixing up the gene pool.

已有证据开始显示，在世界不同的地有过多次不同向的古人的迁移和扩散，所在这些融人了整个人的基因库当中。

Turns out that before the spore dispersal, the mushrooms released water vapor.

If you're a tree, seed dispersal and germination is a pretty risky business.

如果你是一棵树，你会明白把种子散播出去并生根发芽是一件很具有风险的事情。

The maps can also be used to study things like ecotones, the boundary between two habitat types, species dispersal and the migration patterns, and even determine when a species was found in a new area.

这些地图还可以用来研究过渡带，两种栖息地之间的边界，物种扩散和迁移模式，甚至可以确定一个物种何时在一个新的地区被发现。

Really, all of these loose connective tissue proper types share an airy dispersal of fibers... which is why they're easier to eat after cooking — and why you can pull cooked chicken skin apart.

真的，所有这些松散的结缔组织有一个通风的纤维分散，这就是为什么烹饪后它们更容易食用，以及为什么你可以把煮熟的鸡皮拉开。

Taken with the rapid overall increase in immigrants in the past decade or so, this dispersal may be one reason why immigration has become so controversial.

过去的10年内总移民量飞速上升，可能是导致移民变得如此有争议的原因之一。

Mindlab International director David Lewis said: " We tested the physical properties of 15 most popular types of biscuits, along with aspects of their consumption such as 'dunk ability' and crumb dispersal."

“我们测试了最受欢迎的15种饼干的物理属性以及它们的食用属性比如耐浸泡性和易散碎性。”

To explain this, it is necessary to take into account winter winds (which facilitate long-distance dispersal) along with the availability of deep snow and soil nutrients (which promote plant growth).

为了解释这一点，有必要考虑到冬季风（有助于长距离的扩散）以及深厚的积雪和土壤养分（可促进植物生长）。

Spyrou and her team of disease detectives teamed up with archaeologists, looking for clues to the plague's arrival in Europe and its subsequent pattern of dispersal.

斯派尤及其疾病检测团队与考古学家合作，寻找鼠疫抵达欧洲及后续传播模式的线索。

Another fresh hornet queen, found 15 miles southwest of the next nearest find, suggested either a repeated influx from overseas or a vigorous dispersal by the hornets.

另一个新的大黄蜂王，在下一个最近的发现地西南 15 英里处被发现，这表明要么是海外的反复涌入，要么是大黄蜂的大力散布。

So they had to find another way over, and our best understanding at the moment is through what we call oceanic dispersal via rafting.

所以它们不得不另寻出路，我们目前最好的理解是通过我们称之为“漂流的海洋扩散”的式。

And so being able to have a precise chronometer we can relate things like speciation events, or dispersals of various life forms.

我们可以通过一个精确的时钟将各种事件关联起来，比如物种起源或各种生命形式的分散等。

There were earlier smaller dispersals of Homo sapiens out of Africa before the most important migration 60,000 to 70,000 years ago.

早在6万到7万年前最重要的迁徙之前，智人就有过从非洲向外的小规模迁徙。

No clear routes across the Mediterranean from North Africa appear to be present, so the earlier dispersals out of Africa and into Europe and Asia might have been across the Arabian Peninsula.

目前还没有从北非穿越地中海的明确路线，所以早期从非洲到欧洲和亚洲的传播可能穿过了阿拉伯半岛。

A good year for seed dispersal is called a mast year.

一个有利于种子传播的年份被称为 “丰年”。

And grazing rabbits, rodents, and humans are often a highly effective mode of spore dispersal for other mushroom species.

对于其他蘑菇种来说，食草的兔子、啮齿动物和人通常是孢子传播的高效模式。

He said the study " is a story about us and our history - our goal was to unravel some of the mystery about our evolution and our worldwide dispersal."

他说，这项研究“是一个关于我们和我们历史的故事——我们的目标是解开我们进化和全扩散的一些谜团。”
