“The similarities between E. Lambei and E. Caballus are easy to explain: full DNA analysis proves they are the same species. I think it is remarkable all horses in the world today originated from North America and these pretty ponies. Excellent forensic art. ( not really extinct species though, just a very old ancestor…like Kennewick man is to us). Reminds me of Haflinger ponies.” ~Audrey Lively
