Question
Learning goal 3: Determine which of the following are examples of evolution.White fur becomes common in a population of wolves over thousands of yearsA tadpole turns into a frogA population of turtles develops longer necks over many generationsA dog learns to sit and stay after weeks of training
Solution
-
White fur becomes common in a population of wolves over thousands of years: This is an example of evolution. The change in the commonality of white fur in the wolf population over a long period of time suggests that this trait has become more advantageous for survival and reproduction, leading to its increased prevalence.
-
A tadpole turns into a frog: This is not an example of evolution. This is an example of development or metamorphosis, which is a part of an individual organism's life cycle, not a change in the characteristics of a population over generations.
-
A population of turtles develops longer necks over many generations: This is an example of evolution. The development of longer necks in a turtle population over many generations suggests that this trait has become more advantageous for survival and reproduction, leading to its increased prevalence.
-
A dog learns to sit and stay after weeks of training: This is not an example of evolution. This is an example of learning or behavioral adaptation, which is a change in an individual's behavior due to experiences or training, not a change in the genetic characteristics of a population over generations.
