基佬和直男也是共同的祖先{:8:}

猫的生存时间好像比狗长。{:17:}

具体怎样，咱也不知道，不过天朝外面似乎跟天朝的科普说的完全不一样，猫和狗可能没有共同祖先

可能的共同起源是：All modern carnivorans, including cats, evolved from miacoids, which existed from approximately 65 to 33 million years ago. Miacoid species gave rise to Proailurus (meaning "first cat"; also called "Leman's Dawn Cat"), which appeared about 30 million years ago, and is generally considered the first "true cat".[2] However, there were other cat-like species before Proailurus, but not within the family of the order Carnivora.

但是，进化论中出现了断代，没有化石

The cat gap is a period in the fossil record of approximately 25 to 18.5 million years ago in which there are few fossils of cats or cat-like species found in North America. The cause of the "cat gap" is disputed, but may have been caused by changes in the climate (global cooling), changes in the habitat and environmental ecosystem, the increasingly hypercarnivorous trend of the cats (especially the nimravids), volcanic activity, evolutionary changes in dental morphology of the Canidae species present in North America, or possibly even attributed to patterns of periodicity of extinctions (climatic/floral cycles called "van der Hammen cycles"

总之，要承认猫狗共同起源，必须承认进化论，现在对进化论的争议很大

想知道你会进化成那一部分吗
