The black bellied seed cracker, Pyrenestes, is a West African finch. Within the same geographic region, two subspecies of the fi
nch are found. One subspecies has a large beak, which is efficient at cracking the hard seeds of the sedge, Scleria verrucosa. The other subspecies has a small beak, which is more efficient at eating the soft seeds of the sedge, Scleria goossensii. What type of selection occurred to produce this situation
Disruptive selection is simply referred to as an evolutionary force which brings about the division in a particular population thereby leading to a situation whereby the organisms that have an intermediate traits have a lesser reproduction than those with extreme traits who then reproduce more. Based on the question, disruptive selection will affect the regions involved.
