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. A population of rattlesnake goes extinct as the water resources in their environment dry up during an extreme, prolonged drought
B. A population of artic foxes develop a brown fur color as warmer temperatures reduce the number of days of snowfall in the area
C. A population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season
D. A population of frogs develop greener skin after a hurricane blows away the white flowers in the environment
C. A population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season
This observation supports the idea that increased competition causes changes in a species because the larger antlers give the deer a competitive advantage in mating, allowing them to pass on their genes for larger antlers to the next generation. This shows how natural selection can drive changes in a population in response to competition for mates.
