When you’re a human evolution nerd like I am, you need to be discriminating about the source of your information. It’s sometimes eye-rolling how big media hears about some kind of research or fossil discovery & immediately morphs it into a story about sex or food. Well, we are human, & we do love food (it’s one of my blog categories, after all), we do love stories, & we do love sex (..although that priority order may vary depending on one’s gender, age, love of fiction novels, chef-ing proclivities, etc.).
Just so you know, I always try to take a look at the source research when I tell you something or use a link in my posts. I don’t always read entire technical papers, but I do try to ferret out the science from the media hype. That’s why I’ve done a test to find out
- hypothetical Denisovan great great great..etc grandma
if I really do have Neandertal genes, as reported recently for many of us with European ancestry.
I know you’ll be thrilled (& not surprised) to know that I do. & so, probably, do most of you, unless your ancestry is exclusively from Africa, & even then there might be a little Neandertal or Denisovan mixed in if your ancestors left Africa then returned after a little hanky panky with the relatives.
The test I did with the National Geographic Genographic program informed me that 1.8% of my mtDNA (which means from my mother’s side) is Neandertal, and even more, 2.8%, is Denisovan. I hadn’t even heard much of these latter ancestors until the past year or so: these close relatives of Neandertals are thought to have migrated out of Africa around the same time as their brethren Neandertal folk, around 300,000 years ago, & to have lived in central Asia. That Denisovan percentage of my mtDNA is probably related to the 16% of my heritage that’s ‘Southwest Asian’, the rest being Northern European (46%) & Mediterranean (35%).
In case you don’t follow the exciting but admittedly sometimes obscure twists & turns of human evolution research & discovery: the current theory about our Neandertal cousins – advanced hominids who survived a major ice age in parts of (what is now known as) Europe – is that they did NOT become extinct because we, ‘human’ primates, killed them off with our superior brain power, sharper hunting spears, advanced language abilities, or murderous ways when we migrated out of Africa about 80-60,000 years ago. Instead, we now know that they interbred with us. Yes that’s right, we & Neandertals were enough of the same species 60-40,000 years ago that we together became one or more of many varieties of the human primate species we are today.
What I find deeply satisfying about all of this is that we’re living in a time when our understanding of evolution, & human evolution specifically (because we do love stories about ourselves), changes with nearly each new hominid fossil &/or DNA analysis tool. I enjoy my self-proclaimed job of helping you, dear friends near & far (known & unknown, & who are busy with other worthy endeavors), keep up with the latest human primate genealogy news.
And, I also absolutely love knowing that these cells in my body can be linked with people in Africa & Asia & Papua New Guinea & Neandertals & Denisovans & many of the rest of our primate ancestors. Thank you, science, & remember, when you think about human evolution, visualize spaghetti.
Enjoy the Summer Solstice tomorrow, & don’t forget about the big moon this Sunday!


camping trips to Dinkey Creek, Saturday afternoons around our SoCal pool. My mother was constantly (with some exasperation) cleaning up random bits of peanut shell & skin from wherever Russell had most recently consumed his frequent legume feast. This obsession didn’t translate into votes though – my father couldn’t abide Jimmy Carter even though he was the most famous peanut farmer since Thomas Jefferson.
you ask me…) is a very interesting kind of plant which starts growing its bean pods above ground then the pods droop down & finish up their seedpod development underground (wow…isn’t evolution fantastic?!…this plant survival strategy is called
NowIlaymedown tosleep praythelordmysoultokeep ifIdiebeforeIwake praythelordmysoultotake. “If I die before I wake”?! Whoa, that was some serious praying our Lutheran parents taught us. But it was the subsequent godbless part that I paid attention to as I grew older (& didn’t have to say my prayers out loud): godblessmommy&daddy&linda&nancy& sandy&john&skipper[the dog] eventually evolved to include girlfriends who were mad at me (pleasegod make Gloria like me again), boys I had crushes on (these innocents will go unnamed), objects I coveted (pleasegod I really want an electric blanket for Christmas…whoa, what?!), etc. Did I expect God to answer my prayers & fulfill my desires? Not really – as a general rule it seems those Lutherans had low expectations about God’s availability for their particular problems. Was it helpful for me as a child to have this daily bedtime ritual? You bet. Maybe I can figure out a way for my grandson to pray to the planets each night…hey, our ancestors already did that, didn’t they? Maybe a prayer to Black Holes? (hmmm, not sure about that…) Or maybe we can think about reinventing the term prayer to mean something other than human<->God communication?






The freezer! – geez, how lucky are we to have
