Today, we would like to talk about the differences between men and women. You might say that you’ve known about these differences for your entire life, but it’s not that simple. We are sure that we’ll be able to highlight a few facts you’ve never heard of before. And in the bonus section, you’ll find out where the fashion for high heels came from.
The length of fingers
Let’s conduct a short experiment. Place your hand on a flat surface and compare the length of your index and ring fingers. In general, in women, the index finger is longer. In men, the ring finger is longer. How can this be explained?
According to scientists, the length of these fingers depends on the level of male and female hormones that affect the fetus in the womb. So, the reason why the ring finger is longer than the index finger in men is testosterone.
The skin on the heels
Scientists have found out that women’s skin is more hydrated in the décolleté area and on the hands. Only the skin on their heels is dryer than that of men. So, in equal conditions, men’s heels will be smoother.
Breast
You might think, “Why would a man need nipples?” It might sound strange but every person was initially female. When an embryo begins to develop in the womb, the male Y chromosome doesn’t immediately start working.
During the first 5-6 weeks, development occurs only under the influence of the X chromosome, so the nipples have enough time to form. If the embryo is male, the Y chromosome “turns on” after this period of time, and a boy is formed.
Men can even produce milk. Lactation is activated under special conditions, for example, it may appear during treatment with the hormone prolactin.
Vision
Women are better at seeing colors, but men are good at tracking fast-moving objects. This is probably linked to our hunter-gatherer past when men were hunters and women were gatherers.
For example, an orange may appear redder to a man than to a woman. The grass is almost always greener for women because green objects appear more yellow to men.
Gaining muscle mass
Many women have to go to the gym regularly to have a toned body, while a man can just lift a barbell a couple of times to get a 6 pack. So, what is the “ingredient” responsible for muscle development? If you guessed testosterone, you’re right.
In women, it is also produced, but in much smaller quantities. So, it is easier and faster for men to gain muscle mass.
Hair loss
Going bald after the age of 50 is typical for around half of men (and for a quarter of women too). The reason for this is a widespread hereditary disease, androgenetic alopecia, which is also called “male pattern baldness.” Due to this condition, hair follicles shrink, and hair becomes thinner and shorter, and eventually disappears.
Follicle shrinkage can be caused by sensitivity to dihydrotestosterone, a by-product of testosterone. This means that the more muscle-building hormone a man has, the more likely it is that he will become bald.
Adam’s apple
Both men and women have an Adam’s apple, but it’s more prominent in men. Why? The Adam’s apple is the cartilage that protects our vocal cords. It is formed during puberty. Since adult men have larger vocal cords, their Adam’s apple is also more prominent.
By the way, the larger the Adam’s apple, the deeper the voice. There is a theory that our ancestors needed a low voice in order to scare away predators.
Brain size
A man’s brain is larger than that of a woman, but this doesn’t mean that men are intellectually superior to women. Also, some parts of the brain in both sexes are different in size and work differently. For example, the hippocampus, which is involved in learning and creating memories, is larger in women. And the amygdala, which is associated with experiencing emotions and remembering them, is larger in men.
Scientists conducted an experiment: they showed the subjects a video so that they could recall some personal experiences. It turned out that in men, activity was observed only in the right amygdala, and in women, only in the left one.
Beard
At first glance, it might seem that a beard doesn’t provide any benefits. So, why does it grow? There is a theory that the jawline looks more massive thanks to a beard, so its wearer looks stronger and more masculine. Perhaps, our female ancestors tended to choose men with a thick beard as their partners because they thought they would produce healthy offspring with them.
Bonus: Heels
Nowadays, high heels are one of the symbols of femininity, aren’t they? However, in the 17th century, Persian riders used to wear one-inch heels. And since owning horses was a symbol of wealth, heeled shoes also came to signify money and power. The Persians then brought their fashion to Europe.
The French king Louis XIV became a big fan of heels. He even issued a decree according to which only nobles were allowed to wear heels. The higher and redder the heel was, the more powerful the wearer was.
The Sun King only allowed those who he favored the most to wear red heels. But since the 18th century, heels have become a purely feminine attribute, although this didn’t stop rock stars like David Bowie and The Beatles from wearing them.

Tragic events bring orphan colt, mare together
An orphan colt whose mother died shortly after giving birth has a new mom – a mare that had tragically lost her foal – thanks to the generosity of strangers and Washington State University veterinarians playing matchmaker.
Pairing an orphan foal and a nursing mare is a challenging task and one that commonly ends with failure. In this case, the connection was instantaneous.
“The mare had only been without a foal for about 24 hours,” Dr. Lisbeth Matthews, an equine medicine and surgery intern, said. “We walked her into the Veterinary Teaching Hospital and past him. He made a noise, and she went, ‘oh, there’s my foal,’ and started making noises back at him.”
It was a surprise to everyone how quickly the mare, named Shelly but affectionally called Mama by her owners, Roy and Faye Lions, accepted the colt. Equine veterinarian Jenifer Gold, who was helping to care for the foal and to supervise its introduction to the mare, said nursing mares frequently reject orphan foals, and when they don’t, the pairing process often takes days.
“She walked in and started nickering at him like it was her own baby – it was unbelievable,” Gold said. “I’ve been doing this for 20 years, and I have never seen it happen that way.”
The foal, which has been named Laredo, was admitted to the teaching hospital by his owner, Spokane resident Rachel Williams, just days after he was born when he started showing troubling digestive issues. Shortly after the colt arrived in Pullman, Faye Lions placed a call to WSU to see if the equine team was aware of any orphan colts needing a nursing mare.
“Our foal was dead, and nothing was going to bring it back, so we were hoping we could help someone else,” Faye Lions said. “It just so happened there was a foal there.”
A day later, the colt and Shelly were introduced.
“For them to be so willing to basically hand over their animal to a complete stranger after experiencing their own tragedy was pretty phenomenal,” Williams said. “I feel like in this scenario it was the worst of the worst for everybody, but there was a little bit of silver lining to the story.”
Williams is also grateful for the care and treatment she and her foal received at WSU.
“I just can’t even find words to say how great the veterinarians at WSU were,” she said. “They went above and beyond. I am just happy I ended up at WSU. I am so glad we were able to match those two up – it is kind of a miracle.”
Shelly will live with Williams until the colt is ready to be weaned, likely in six months, before she will return to her home in Kamiah, Idaho.
“It will be tough to say goodbye because you just naturally start to bond with animals, and she has kind of been my lifesaver,” Williams said. “It will be bittersweet for sure, but I am sure her owners will be happy to have her back.”
During the spring, the equine team at WSU typically sees at least a handful of orphan foals. Equine medicine specialist Dr. Macarena Sanz said orphan foals can be fed a powdered milk formula designed for horses, but those raised by humans typically develop behavioral issues that can become problematic as the animal matures.
“They turn out to be socially weird, have no understanding of personal space, and they are more difficult to train,” WSU equine veterinarian Macarena Sanz said. “The fact that this orphan foal has a mare is really going to make a difference.”
Sanz strongly encourages owners to immediately call their veterinarian if a foal is orphaned, as early care is critical to the animal’s survival.
