In this case we can say that "The cheetah gave the gazelle it's speed".
The explanation to this is that when cheetahs hunt down the gazelle, they only try to catch the slowest of the herd, leaving the fastest gazelles to mate and pass their genes to the next generation. Therefore the next generation of gazelles would be fast. However for the cheetah to catch their food, they must be faster than the gazelles. Hence, the slowest cheetahs were not able to hunt a gazelle, and starved and died, leaving the faster cheetahs to mate and pass their genes to their offspring. This is the reason why cheetahs are still faster than gazelles.
