Higher levels of UV light on land

Explanation:

The algae began to appear because of the presence of ultraviolet light that was emitted by sunlight, this generated the increase in temperature of the waters, therefore under the glaciers the perfect climax was formed so that these could begin to emerge phenomena, not excessive sunlight, the great presence of oxygen, is what led to the appearance of these algae.
