Explanation:
The very primitive and early microorganisms on the earth's surface were protobionts. Protobionts are cell-like microscopic structures, and they are made up of organic and inorganic molecules present in a lipid bilayer membrane.

These membranes were selectively permeable and also observed shrinkage and swelling in osmotic conditions. Protobionts also possess the characteristics of reproduction.

so here's my thinking- seeing as how population 1 only has seals with thin blubber they will automatically survive because they won't need to adapt to the environment. but population 2 has both thin and thick blubbered seals and seeing as how the thick blubbered ones will most likely just die out the thin blubbered ones will 'take over'
good luck :)
i hope this helps
have a nice day !!
