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.
