She and her team found that howler monkeys face an anatomical trade-off: a species can either have a really big hyoid bone, or it can be very well endowed. But not both. That finding is in the journal Current Biology. Those species with bigger hyoids live in single-male groups, so it makes sense to invest in what the researchers call "precopulatory traits," that is, their courtship strategy of attracting the female's attention. But in a species where groups include multiple males, the best way to ensure passing on more genes is to make more sperm—by building bigger testes. The researchers say the finding is the first evidence for an evolutionary tradeoff between mating calls and sperm production. And they warn that while human women do tend to prefer males with deeper voices, we men advertise ourselves in many other ways as well. So don't go clicking that pop-up ad that promises to enlarge your hyoid.

Printed "cleavages", the speaker says "researchers"

Explanation: On the recording the words are "what the researchers call". The printed word "cleavages" starts with a different letter, so listen from the start.

Printed "methodical", the speaker says "multiple"

Explanation: Listen again to "groups include multiple males". Both words start with the same letter, but the spoken word is shorter.

Printed "gayety", the speaker says "evolutionary"

Explanation: In the audio you hear "an evolutionary tradeoff". They start with different letters, and the printed word is much shorter.

Printed "paymentof", the speaker says "tradeoff"

Explanation: Here the speaker says "an evolutionary tradeoff". The printed word "paymentof" does not make sense here, so trust the audio.

Printed "afterwords", the speaker says "promises"

Explanation: The speaker says "promises to enlarge your hyoid", not "afterwords". The two words begin with different letters, so listen to the first letter.

"Current" matches the audio

Explanation: "in the journal Current Biology". The journal name may look special, but the speaker says it exactly, so do not click it.

"hyoid" matches the audio

Explanation: "a really big hyoid bone". The word hyoid is rare, but the speaker says it exactly, so do not click it.
