How is laying eggs on land an evolutionary advantage for sea turtles and capelin

1. Laying eggs on land reduces the chances of the eggs being predated on by predators in the seas and oceans.

2. Temperatures are critical in the development of the yolk into an embryo and full turtle. Temperatures even determine the sex of the developing turtles. Land heats up more than water hence promotes faster development hence increases the survival of the offsprings.
