Question

What do both rate of speciation models have in common?

a) They both focus on geographic isolation
b) They both consider reproductive barriers
c) They both involve gradual change
d) They both exclude genetic drift

Answer 1

Both rate of speciation models have in common reproductive barriers, gradual changes over time, and the consideration of natural selection and other factors.

Step-by-step explanation:

Both rate of speciation models have in common that they focus on reproductive barriers as a mechanism of speciation. These barriers create a separation between closely related species, allowing them to diverge and become genetically independent. Both models also involve gradual changes over time, although one model illustrates slow change and the other shows rapid change. Additionally, both models consider the influence of natural selection and other factors such as gene flow, genetic drift, and mutation.
