I stumbled upon this sentence on p.82, in Chapter 5A, in the textbook "Reading Explorer 4" by National Geographic.
The sentence goes, "It found that people of African descent had twice as many genetic differences from each other than as did others." Here, they talk about the evolution of the human beings.
This sentence means that it found that African descendants had twice as many genetic differences from each other as others, right? The so-called as ... as structure is ok, but what is the use of "than" before the second "as"? Could you tell me how the word "than" grammatically work here in this sentence?
Thank you for your help in advance.
