Male bowerbirds build intricate structures to attract mates. Structures do not improve survival but increase mating success. This behavior is an example of:
A population of frogs develops a mutation that enhances mating calls. Over generations, the frequency of this allele increases. Which of the following best explains this?
Which best explains why natural selection cannot act on acquired traits?
Which scenario best illustrates intraspecific variation interacting with abiotic selection pressure?
Which of the following is an abiotic selection pressure?
How can environmental factors influence evolutionary change in a population?
Which of the following would likely lead to increased selection pressure within a population?
A male bird’s brightly colored feathers attract more mates, but make it more visible to predators. What does this trade-off illustrate?
What made Darwin’s theory of natural selection so influential?
Which best describes the evolutionary significance of random mutation?
