550
600
500
700
650

Answer 1

In the given scenario, if all mammals today evolved in 65 million years from a common ancestor and one species took 100,000 years to evolve, the number of ticks (representing the number of species) would be 650.

Step-by-step explanation:

In the given scenario, if all mammals today evolved in 65 million years from a common ancestor and one species took 100,000 years to evolve, we can calculate how many ticks (representing the number of species) would be needed to reach this time frame.

To do this, we divide the total number of years (65 million) by the time it takes for one species to evolve (100,000). The calculation is: 65,000,000 / 100,000 = 650 ticks.

Therefore, the correct answer is 650.
