How can their be similar characteristics of two diffrent speices, such as a tiger and cheetah. explain.
Species can share similar characteristics. However, a species is defined as a group that can interbreed/produce offspring with another member of that group. Cheetahs and tigers are different species because they can't breed with each other, but they do share many other characteristics, both being predatory big cats.
In shore they are related (share a common evolutionary ancestor)
