Question

how do scientists determine what foods were eaten by extinct hominins such as neanderthals? in the past, researchers were limited to studying the marks found on the fossilized teeth of skeletons, but in 2017 a team led by laura wyrsch of the australian centre for ancient dna tried something ______ the dna found in neanderthals’ fossilized dental plaque. which choice completes the text so that it conforms to the conventions of standard english? choose 1 answer: a new. sequencing b new: sequencing c new; sequencing d new, sequencing

Explanation:

The colon is used to introduce an explanation or example. Here, "sequencing the DNA..." explains what the "something new" is. A semicolon is used to separate independent clauses (which is not the case here), and a comma would not properly introduce the explanation.

Answer:

A. new. Sequencing
