▸ After a dry period lasting many years, only a few individuals of a tree population survive and then produce drought-tolerant offspring.
This statement provides the best evidence because it shows that the environmental change (dry period) directly influenced the traits of the offspring produced by the surviving individuals, leading to a population better adapted to the new environment.
Which statement provides the best evidence that an environmental change can affect traits in later generations of an organism's population?
A The number of plankton begin to decrease as the pH of ocean water decreases.
℗ Above-average rainfall causes the number of lichens growing in a forest to increase.
© A type of plant that had rarely been observed in a particular habitat suddenly produces more offspring as winters become milder.
