| During the last ice age, massive glaciers covered much of our planet. However, a region of Alaska, Siberia and the Canadian Yukon remained ice-free. This region, known as Beringia, supported unique organisms and was an important haven for evolution. Now, scientists may have uncovered how Beringia supported such diversity at a time when conditions for life were harsh. |
