    1. A population of monkeys on an island in the Amazon river is preyed upon by margays (a type of small cat).  Within this population the largest monkeys are too big for the margays to catch and the smallest monkeys are too agile for the margays to catch. Thus the mid-size monkeys have the lowest fitness. Over time this population could potentially split into two populations and two separate species of large and small monkeys. What type of speciation would occur...
