Summary: Scientists have shown that changes in coat color in computer mice are the outcome not of a single anomaly, but several different anomalies, all within a single genetics.

Which mice made it through much better on the lava circulation clarify?

The video clip recommends that on the dark lava flows, dark- colored rock pocket mice are much more numerous than light computer mice. A survival benefit of 1% for dark rock pocket computer mice on a dark background, starting at 1% of the population, would cause 95% of the computer mice having dark hair in 1000 years (6:18).
