I am a human. I am Kingdom Animalia, Phylum Chordata, Class Mammalia, Order Primates, Family Hominidae, Genus Homo, Species Homo sapiens sapiens. My species is alone in its genus–has been alone for many thousands of years–but our lost genus-mates live on in our genes. They certainly live on in mine.
I am a human of European descent. I am fourth-generation Czech, third-generation German, and third-generation Irish on my father’s side. My mother’s side of the family can be traced back to the second ship of settlers that came to North America from England; her side of the family is English and Irish and French and Welsh and Scottish… But because I have such strong European ancestry, it is a given that I have genes from the lost species Homo neanderthalensis–the Neanderthal.
