How old were the earliest fossils?

• 4.6 billion years ago

• 3.9 billion years ago

• 3.5 billion years ago

What was the first genetic material?

To withstand selective pressures, populations need

• To have low genetic diversity

• To have high genetic diversity

Answer explanation

As the environment changes, the population must have a trait that allows for the population to survive. The more genetic diversity in the population, the more resilient to changes in the environment (withstand selective pressure)
