Neanderthals Listened to the World Much Like Us

Neanderthals Listened to the World Much Like Us

If you were somehow able to travel back in time some 130,000 years and chance upon a Neanderthal, you might find yourself telling them about some of humanity’s greatest inventions, such as spanakopita and TikTok. The Neanderthal would have no idea what you were saying, much less talking about, but they might be able to hear you perfectly, picking up on the voiceless consonants “t,” “k” and “s” that appear in many modern human languages. ....

The researchers discovered chemical signatures in the corals’ biology or biomarkers, that are present in organisms that were most resistant to the bleaching. This previously hidden insight could help researchers and conservationists better restore and protect reefs around the world.
“Usually, we think of biomarkers as signatures of disease, but this could be a signature of health,” said Robert Quinn, an assistant professor in
MSU’s Department of Biochemistry and Molecular Biology. “This could help us restore reefs with the most resistant stock.”
Corals are symbiotic communities, where coral animal cells build homes for algae that provide them energy and create their colors. When corals bleach, however, the algae are lost and leave behind bleached skeletons that are susceptible to disease and death. ....
