Saey writes, “Big cats and domestic cats last shared a common ancestor about 11 million years ago. Usually genomes get scrambled as species evolve…cats both big and domestic ‘are very well adapted, successful evolutionary machines’” (4). Since big and small cats are very different in size and habitats, but similar in structure, they are related. They are not that closely related, though, because they have not had a similar ancestor in several million years. They have evolved quite a lot from this common ancestor into what they are …show more content…
Holland writes, “Previously, the oldest fossil evidence came from Africa and put the big cats at 3.8 million years old. But modern geographical patterns and molecular data—DNA comparisons of ancient fossils with modern bones—suggested Asian origins going back at least six million years” (1-2). The finding of fossils is essential to knowing how long ago modern cats evolved and understanding how and how much they evolved over millions of years. Also, since modern big cats were probably the first modern-day cats to develop and evolve, scientists and researchers need to know how they developed so they can better understand how small cats like housecats evolved. Fossil evidence is very important in figuring out the evolution of cats over time. Moreover, humans loved the little, soft, furry cats, so they took them into their homes. Lusted writes, “Cats probably domesticated themselves: people wanted them, and so they fed them, and cats gradually grew used to people and began living with them” (3). Cats used to be wild and live in the wild, but over the years, they have learned how to get along with humans. They have learned how to live with humans in houses. Cats have evolved over several years into animals that are friendly to humans and domesticated
