"They might be tightly linked to the development of soil on land," said Dr. Baldauf, the Swedish biologist, who is analyzing the DNA of species discovered in the Eumycetozoan Project.
“他们或许与陆地土壤的变迁有紧密联系，”瑞典生物学家巴尔道夫说。他正在对黏菌工程中发现的黏菌品种进行DNA分析。
Instead of analysing the genome of a specific organism, scientists sequence all the DNA they find in environmental samples, ranging from seawater to soil.
有别于分析特定生物的基因组，科学家对取自海水、土壤等自然界的生物样本，统统进行DNA测序。
Essentially we can take a sample of soil or air — and in our case — water, and we can sequence the DNA out of it and tell you what is there.
从本质上讲，我们可以提取土壤或空气的样本。在这个例子中，我们提取的是水，我们可以从中测定出DNA序列，从而得知存在什么生物。
