So i'm going to distinguish between micro and macroevolution.
00:05
So i've got two populations that i drew here.
00:08
The black represents the animals and the green will represent their primary food source.
00:15
So first we're going to deal with microevolution, which is going to occur on this population.
00:21
Microevolution only occurs at the population level.
00:25
It occurs, for example, if there is a sudden increase in the number.
00:30
Number of blue food sources available compared to green.
00:34
Some of the population will be able to consume those or evolve to consume those based on random shape.
00:47
Eventually, the entire population would be capable of having the blue food source...
