Name- Cheetah (Acinonyx Jubatus)
Adaptations- The cheetah has longer legs than other wild cats, and a longer spine. It also has retractable claws unlike most cats, for traction. The cheetah has an extremely long tail, which is used for balance for running, and has a larger heart and lungs than most big cats used to produce more oxygen while running.
Causes of Adaptations- The cheetah and different subgroups of cheetah(from other parts of the world) come from one main ancestor known as Acinonyx Kurteri. The legs and spine come from the cheetah's excessive running. Over time the legs have adapted to make th cheetah built for speed as its prey was probably very fast. Primitive cheetahs might have had retractable claws, but always kept them out when running for traction. Over time, as cheetahs began to run more, the slowly began to lose the ability to retract their claws, giving them amazing traction. Their tail has grown longer, for balance when running, tying in why they have a longer spine and legs. Scientist have found fossils that have larger sinus cavities and larger ribs where cheetahs had large lungs. Cheetahs today have larger hearts and lungs, used for supplying oxygen throughout the body while running.
This is an example of modern evolution, for other big cats did not evolve this way. Tigers and lions are more bulky, because they used stealth or stamina, but the cheetah uses speed to catch its prey. These adaptations have helped the cheetah to catch its fast prey in its harsh environment.
