Speciation through Natural Selection

Create a series of diagrams that show the 3 steps of speciation, detailing how adaptation includes the process of natural selection for Utenstil-beaked hornet-birds(Population) Separation: SKETCH a population of Utensil-beaked Hornet Birds with a roughly equal number of fork and spoon beaks in Bean LandSKETCH a group of Hornet Birds (both fork and spoon bills) flying to Apple Land to form a new population, leaving behind a population with a roughly equal number of fork and spoon beaks in Bean LandAdaptation: use side by side panels for Bean Land and Apple Land to show different adaptation in different environmentsSKETCH parents and many offspring Hornet Birds in Bean Land. Show Overproduction and Genetic Variation by including many young Hornet Birds with both beak types and very few beansSKETCH parents and many offspring Hornet Birds in Apple Land. Show Overproduction and Genetic Variation by including many young Hornet Birds with both beak types and very few apple slicesSKETCH one fork beak eating a bean, showing how that trait is less favorable for beans AND show one spoon beak eating a bean, showing how that trait is more favorable for beansSKETCH one fork beak eating an apple slice, showing how that trait is more favorable for apple slices AND show one spoon beak eating an apple slices, showing how that trait is less favorable for apple slicesSKETCH spoon beaks surviving and reproducing (show offspring with spoon beaks) and fork beaks not surviving in bean land SKETCH fork beaks surviving and reproducing (show offspring with fork beaks) and spoon beaks not surviving in apple land SKETCH a population of spoon-beaked Hornet Birds in Bean Land (the fork beak went extinct) many generations laterSKETCH a population of fork-beaked Hornet Birds in Apple Land (the spoon beak went extinct) many generations later(Reproductive) Division: in Bean Land, where apple slice trees have begun to growSKETCH two fork-beaked birds from Apple Land that have flown back to Bean Land and are near, but separate from a group of spoon-beaked Hornet Bird pairsSKETCH several spoon-beaked bird pairs with spoon-beaked offspring, and the fork beak pair standing apart with fork-beak offspringEXPLAIN why Fork-beaked Hornet Birds are now a separate species from Spoon-beaked Hornet BirdsADD labels and a brief description for each sketch that makes the sketch easier to understand
