Mexican gray wolf – a little guy as wolves go, perhaps because life in desert mountains is hard. Looks more like a coyote than the big wolves of Yellowstone.
Can a word become more important than the thing it names? I’ve thought about this before. We humans stuff nature into neat little categories because it makes a complex world easier on our brains.
We divide living things into species.
But what is a species?
A species is often defined as a group of individuals that actually or potentially interbreed in nature. In this sense, a species is the biggest gene pool possible under natural conditions… That definition of a species might seem cut and dried, but it is not… many plants, and some animals, form hybrids in nature.” berkeley.edu
If you add deep time to your definition, you’ll find “species” come and go on Earth despite the fact that evolution is a continuum.
Like a lot of the labels humans create, a species is a handy way to mostly-categorize and sort-of talk about an important topic. The word is fuzzy, but that doesn’t usually matter.
Until it does.
In America, we have a law (much loved and hated) that requires we spend money and limit certain economic activities to save “threatened and endangered species.”
Most Americans live in urban/suburban areas and never see large predators, but want to protect them. Rural folk like myself actually live with them, lose cattle and pets to them, and sometimes fear for human lives. My urban/suburban friends may get a taste of living with predators because some wolves (and definitely coyotes) live in their parks and backyards.
Total disclosure – I own no cattle, lost two pets to bears, and am willing to protect predators but think the government often handles the projects badly.
That brings me to the American Wolf. If gray wolves, red wolves, eastern wolves, and Mexican grey wolves are four species, they must be protected in all their various ranges. Science tells us something about this question:
- Eastern and red wolves are genetically coyote/wolf hybrids – Princeton-UCLA study published in Science Advances
- Mexican grey wolves come from a tiny captive stock (true as far as I know) and have interbred with coyotes and domestic dogs (common assertion here in Mexican grey wolf country – I can’t say, but it seems plausible.)
Researchers analyzed the complete genomes of 12 pure gray wolves (from regions without any coyotes), three pure coyotes (from regions without any gray wolves), 6 eastern wolves, and 3 red wolves. The results showed that eastern wolves are about 75 percent gray wolf and 25 percent coyote, while red wolves are about 25 percent gray wolf and 75 percent coyote – with almost no unique genetic material of their own.” csmonitor.com
(Too bad my local Mexican grey wolf was not included in the study.)
Pro-wolf and anti-wolf groups have entrenched mutual distrust in my area. Their conflict runs so deep that beating the other guy often seems more important than the wolves.
So choose your side and remember that, in government, a word means whatever the law or the courts say it means. Which will not be what science or common-usage says it means. Remember your opponents are probably nice people with reasonable goals – try to keep an open heart so you can keep an open mind.
Maybe haiku will help:
Coyotes mate wolves
But Danes and Chihuahuas can’t
So what’s a species?
