Question

What is evolution?
A) a rare event
B) a process that is constantly occurring at the same rate in all organisms
C) a process that occurs as a result of differences in reproductive fitness
D) a process that occurred only in the past

Accepted Answer

Evolution is a process that occurs as a result of differences in reproductive fitness, meaning that organisms with certain traits are more successful at reproducing and passing on those traits to their offspring. This leads to changes in the genetic makeup of populations over time. Evolution is a continuous process that is ongoing in all organisms, not just a rare event or something that only occurred in the past.
