For thousands of years, there may have been around just 1,280 breeding individuals sustained the human species, an evolutionary bottleneck that nearly caused the species' extinction.

Genetics study lays bare Ice Age drama for humans in Europe

March 05, 2023 8:05 am

Researchers on Wednesday unveiled an analysis of genome data from 356 hunter-gatherers who lived in the region between 35,000 and 5,000 years ago, a span that included the Ice Age's coldest interval between 25,000 and 19,000 years ago.

How about them apples? Research orchards chart a fruit’s future

September 28, 2022 5:51 pm

Scientists are working on understanding the genetics that result in the bonanza of apple diversity, with the ultimate goal of improving the fruit in different ways — tastier, heartier, more disease-resistant and with longer shelf-life in the face of changing climates.

Here's why we age
