What had the legs of a gator and the jaws of a fish? Why, the earliest land animals. Because a new study shows that animals evolved weight-bearing limbs long before they had the chompers to really take advantage of a terrestrial diet. The research is in the journal Integrative and Comparative Biology. Scientists had suspected that the first four-legged creatures to haul their carcasses out of the ocean didn't belly up to the salad bar straight away. But they lacked definitive proof. Now, researchers have carefully examined the fossilized faces of 89 beasties that lived on land and sea some 300 to 400 million years ago. They probed the jaws for a range of biomechanical features, such as how much force they could give to their bite. The result: seems it took tens of millions of years after setting foot on land to come up with a mouth that could munch on the greenery.

Printed "euthanised", the speaker says "advantage"

Explanation: On the recording the words are "take advantage of". They start with different letters, so listen to the start.

Printed "additives", the speaker says "carcasses"

Explanation: Listen again to "haul their carcasses". Their first letters differ, so focus on the start of the word.

Printed "minstrelsy", the speaker says "carefully"

Explanation: In the audio you hear "have carefully examined". The two words begin with different letters, so listen to the start.

Printed "bathtub", the speaker says "examined"

Explanation: Here the speaker says "carefully examined the". Listen to the start to hear which word the speaker uses.

Printed "semitropical", the speaker says "biomechanical"

Explanation: The speaker says "range of biomechanical features", not "semitropical". Both words end the same, so listen from the start.

Printed "transitions", the speaker says "millions"

Explanation: Listen for "tens of millions of". The words start with different letters, so listen to the beginning.

"Integrative" matches the audio

Explanation: "The research is in the journal Integrative and Comparative Biology" is a long title. It is spoken exactly as printed, so do not click it.

"'gator" matches the audio

Explanation: "the legs of a 'gator" may look odd on the page. The speaker says it exactly, so do not click it.
