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)
A population of frogs develop greener skin after a hurricane blows away the white flowers in the environment
A population of rattlesnake goes extinct as the water resources in their environment dry up during an extreme, prolonged drought
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

The observation that best supports the idea that increased competition causes changes in a species is:
**A population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season.**
This observation indicates that the changes in antler size are driven by sexual competition for mates, which is a form of natural selection, where individuals with traits that give them an advantage in securing mates are more likely to reproduce and pass those traits on to future generations.
