Correct Transcript:

When it comes to lizard sex, size does matter. But not in the way you might think. Because in the June 4th online issue of the journal Current Biology, scientists say that for at least one type of lizard, larger eggs are more likely to make girls while smaller eggs yield boys. For many animals, the sex of an individual is dictated solely by its chromosomes. But for small alpine lizards, gender isn't so cut-and-dried. The scientists had earlier found that nest temperature can influence the sex of lizard hatchlings. Cooler nests turn out more boys—no matter what their chromosomes say. At the same time, the researchers noticed that larger eggs seemed to make more daughters. But they wanted to put their observation to the test. So they took big eggs and removed some yolk—and, voila, they made males. Adding yolk to a little egg was a recipe for a female.

Printed "hyperlinks", the speaker says "scientists"

Explanation: Here the speaker says "Current Biology, scientists say". "hyperlinks" is on the page, not in the audio. They start with different letters, so listen from the first letter to be sure.

Printed "continuous", the speaker says "influence"

Explanation: The speaker says "can influence the sex", not "continuous". The printed word "continuous" does not make sense here, and the two words start with different letters.

Printed "records", the speaker says "chromosomes"

Explanation: Listen for "their chromosomes say". "records" starts with a different letter and is shorter than the spoken word.

"Current" matches the audio

Explanation: "the journal Current Biology" names a real journal that looks unusual. The speaker says it exactly as printed, so do not click it.

"yolk" matches the audio

Explanation: "removed some yolk, and, voila" sits close to the changed words and may draw your eye. The speaker actually says "yolk" exactly, so do not click it.
