It’s enormous fun to look at cat evolution, because you get to look at cats. Even people who don’t like pet cats are impressed by cheetahs, lions, and tigers.
There are actually more cats out in the wild than most of us have ever dreamed of, including the gorgeous Asiatic golden cat shown at the top of this post.
Today we are going to look at all of them, except for Fluffy and its wildcat relatives. I’m saving them until next time for two reasons:
- The biological line between housecats and their ancestors – the wildcats (one word) – is blurry, so we need to check them out all together.
- We do need to talk about how cats evolved. Even though that happened to wild cats (two words) over millions of years, Fluffy’s history is helpful. Cat breeders have been intentionally messing with its genes for over a century. Is the process that has given us the tailless Manx and the bald Donskoy typical of all evolution? Tune in next time and find out!
The following eight sections are based on the eight genetic lineages that DNA sequencing consistently shows in the cat family. (Johnson and others, 2006; Nyakatura and Bininda-Emonds)
They aren’t presented in the order in which each group evolved – those dates come out differently for different researchers. So far, I think, the only consensus is that there are eight lineages.

Let’s start out with the lineage that contains the cat featured at the top of this post – the Asiatic golden cat, known locally as the “fire tiger.” (Sunquist and Sunquist, 2002)
Then we’ll check out the big cats and the other six lineages.
