Evolution - Gradual Species Change

The video explains how changes in inherited characteristics lead to the diversity of life on Earth, all originating from a common ancestor. It delves into genetic evolution, describing it as a process where certain gene types become more prevalent over time, resulting in a change in gene frequency within a population.

What is the primary cause of evolution as described in the first section?

• Human intervention

• Random chance

• Changes in inherited characteristics

• Natural disasters

According to the second section, how has the diversity of life on Earth developed?

• Through spontaneous generation

• From a common ancestor over millions of years

• By extraterrestrial influence

• Through genetic engineering

What does the third section define evolution as at a genetic level?

• A change in the physical appearance of organisms

• A change in gene frequency of a population over time

• A change in the diet of organisms

• A change in the environment

Which of the following is NOT a factor in the genetic level of evolution?

• Gene frequency changes

• Population size

• Environmental changes

• Common ancestor

What becomes more common in a population over time according to the genetic level of evolution?

• Certain habitats

• Certain behaviors

• Certain physical traits

• Certain gene types
