An anthropologist and paleontologist went on an expedition in South America to search for new fossil remains.
As they began to dig, they later found an unfamiliar fossil remain
They wonder what it looks like during the prehistoric times.
They went back to their local home to visit their friend who is a demographer. They explain about the unknown fossil and asked their friend to sketch the features of this animal.
After the tests, it was then proved that the mitochondrial DNA of both house cats and smilodon shared a common ancestor about 20 million years ago. In conclusion, they found out that the 2 organisms are truly related to each other.
