Ferrets are not rodents

A ferret

Certain misconceptions just won’t go away. While some of them may be virtually harmless, like how a lot of people mistakenly believe Dimetrodon is a dinosaur(it is actually a synapsid, see my post “I don’t eat dinosaurs” for more info), some can have real world consequences on policy and how we live our lives.

One of the more annoying misconceptions I encounter when it comes to the animal kingdom is the idea that ferrets are rodents. I can’t count how many times someone has told me or I’ve overheard someone say “I could never keep a ferret as a pet, they are rodents!”(whether or not true rodents make good pets is beside the issue of this post).

Ferrets are not rodents, they are members of the glorious mustelid or weasel family. Mustelids belong to the large order carnivora, which means they are actually more closely related to other members of carnivora like dogs, cats, and bears than to rats and mice. What ferrets and other mustelids do have in common with rodents is their common mammalian heritage, which would also make them distant relatives to humans.

Yet this kind of ignorance persists, even though it is so easy to correct by merely looking it up online. Why does this misconception matter? There are often local, and state laws against keeping ferrets, and this kind if ignorance can influence policy. It can also affect the attitude some people have toward this animal, or their close relative the badger, which is getting treated like a pestilence in the U.K these days. See articles below for more info on this subject.

Other members of the mustelid family include minks, polecats, and wolverines, the largest and most ferocious of mustelids. Skunks used to be classified as mustelids, but recent genetic evidence has lead to them being reclassified in a closely related group. Don’t worry, skunks have been doing okay since reclassification; they are especially good at stinking up my neighborhood at night.

So this misconception has far more profound implications than thinking Dimetrodon is a dinosaur. Sure, the toy section at the local pharmacy may put the toy Dimetrodons with the dinosaurs, implying it is a dinosaur. Truth be told, Dimetrodon(or “cousin Dimi” as I affectionately call him sometimes, since Dimetrodon is more closely related to us than to dinosaurs) was not a dinosaur and went extinct long before the dinosaurs roamed the earth, but no one is harmed by this.

Other misconceptions that bother me, like Sikhs being thought of as Muslims, or people thinking Turks, Persians, and Pakistanis are Arabs are also disturbing, but that would require another post or two.

The winter reds, and blues

I hope everyone is having a splendid winter so far. Unfortunately, many people find it difficult to engage in outdoor or even indoor exercise this time of year due to the winter blues. Some people may even experience major depression caused by the shorter days, and may find it difficult to crawl out of their warm, cozy bed. If it is very cold outside, some folks won’t even venture outside.

In part, genetics may play a role. Indeed, slowing down and feeling depressed during the winter may be related to the hibernation response in other animals- Metabolic depression in hibernation and major depression: an explanatory theory and an animal model of depression.

This is fascinating research. It’s not necessarily easy to “prove” anything either way with this kind of speculation; even if it were “proven” that depression is related to hibernation, it doesn’t necessarily mean you have to “hibernate” if you feel depressed, unless you are a bear. Understanding that there is a connection between the two could lead to a better understanding of depression and more effective ways to overcome it.

What we know already may already be helpful for some. In many animals, the hibernation response is turned on by light deprivation due to shorter winter days and/or lower temperatures. SAD(seasonal affective disorder) is a form of depression that tends to affect people more during the winter. Lack of light may play a role, and so logically, “light therapy” by using a light box in the morning may be beneficial for those affected – Seasonal affective disorder: an overview.

If you have eye problems though, using a light box may not be a good idea. It doesn’t work for everyone since the brain is very complex and we all have our own unique biochemistry. Some people are more sensitive to light than others. Whatever you do, keep on exercising, and try to expose yourself to extra light in the morning if you have SAD. If you think you have serious depression, seek professional help.

I must admit that I sometimes feel a little blue in the morning this time of year, but a quick juggle or some exercises and turning on all the lights seems to help me quickly overcome it. It is nothing serious luckily. I never drink coffee or caffeinated beverages, so I have to rely on intense exercise, and sometimes eating or drinking something very spicy to help wake up my system.

I don’t joggle early in the morning usually(though I often juggle a little), since I tend to drop the balls too much if I joggle soon after waking(the darkness doesn’t help) and I often don’t have the time anyway. I just do it later in the day. On the rare occasion I do a long, very early morning joggle(I mean around 5:30 AM to 7:00 AM), I notice I am slowly improving. Ideally, I’d like to do more joggling at this time of day, and so I continue to study various approaches to quickly overcoming early morning grogginess without caffeine. I’m open to any new suggestions.
