Unrepentant fan of pumpkin? Then you might consider adding “stone age humans” to your list of people to thank this holiday season. Without them, it wouldn’t be possible to carve jack-o’-lanterns or chow down on a dense, moist slice of homemade pumpkin bread.
A new study suggests that the Cucurbita genus would likely not be around today if ancient humans in the Americas hadn’t domesticated them. More than 10,000 years ago,wild pumpkin and squash species were a major food staple for megafauna like giant sloths ( Megatherium, pictured at right) and mammoths, which ensured the continued survival of these plants by dispersing their seeds across the Americas. When these large mammalian creatures were gradually driven to extinction due to climate change and hunting, many of the wild Cucurbita species died off along with them.
Not all of them, though. Many of the ancient Cucurbita species tasted quite bitter, and while that was fine for the undiscriminating taste buds of megafauna, humans and smaller mammals preferred varietals that were a bit more palatable. As John Bohannon explains on ScienceMag.org, “The smaller mammals that took over in the Americas are thought to be far more sensitive to bitter-tasting plants, since they carry more genes for bitter taste receptor proteins compared to the extinct giants.”
As a result, the gourds that tasted the best to humans were the ones that ultimately survived through domestication in the wake of the quaternary extinction event. To celebrate the continued survival of the wonderfully diverse world of Cucurbita, here are just a few modern day squashes and gourds you might want to consider for your dinner table.
