“A certain species of snail shows variation in its shell coloring, from solid yellow shells to brown, banded shells. Birds are the main predator of these snails. A scientist observed populations of these snail in various habitats. She hypothesizes that the yellow-shelled snails are better camouflaged in grasslands than brown-shelled snails are.”
Question: (part A) Based on the scientists hypothesis, describe how the percentage of yellow-shelled snails most likely compares with the percentage of brown-shelled snails in grassland.
Question: (part B) assuming the scientists hypothesis is correct, explain how natural selection could have acted over time to produce the relative percentage of snails you described in part(a)
