The better to see you: why life emerged from water on to land?

Life on Earth began in water. Therefore, when the first animals came onto land, they had to exchange their fins for limbs, and gills for lungs, to better adapt to the new terrestrial environment. Recently there is a new study which showed that the transition to the lungs and the extremities did not disclose the full picture of the transformation of these creatures. When they came out of the sea, they got something perhaps even more valuable than oxygenated air: information. In the air eyes can see much further than under water. According to Malcolm MacIver, neurologist and engineer from northwestern University, the increased visibility provided the animals for more information about rich food sources close to shore.
