Question

Based on Darwin’s ideas of descent with modification and natural selection, which observation would best support the idea that increased competition causes changes in a species?(1 point) Responses A population of artic foxes develop a brown fur color as warmer temperatures reduce the number of days of snowfall in the area A population of artic foxes develop a brown fur color as warmer temperatures reduce the number of days of snowfall in the area A population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season A population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season A population of frogs develop greener skin after a hurricane blows away the white flowers in the environment

Answer 1

A population of deer showing an increase in antler size over time, which allows them to obtain more mates during mating season, would best support the idea that increased competition causes changes in a species. This is because the larger antlers provide a competitive advantage in mating, leading to a higher likelihood of passing on those traits to the next generation. This demonstrates natural selection at work, where traits that enhance an individual's chances of survival and reproduction become more common in a population over time.
