Did seals get lost in the mix?
I think it’s pretty safe to say that when it comes to evolution, most people typically picture aquatic life forms sprouting legs then coming onto land … not the other way around.
Shockingly enough, a creature almost synonymous with the sea didn’t actually begin that way. And boy, is it a whale of a tale.
A mind-blowing video recently posted by PBS Eons reveals that whales were actually predatory land animals … the same ones that would later become wolves, specifically.
Yep, you read that right. Land animals. With arms and legs and everything.
To explain, we’ll need to go back 52 million years.
Before the warm and rainy Eocene epoch—the same time period that brought us the first horses and bats—whales looked more like the image below.
Something like a mix between a wolf and crocodile, if you ask me.
You know it's hotter under the water.
Yes, animals did move from the sea to the land, bringing us the first mammals. But then, over time, some mammals were like, "nah, it's that ocean life for me." Including some of these fellas.
These creatures first went into the water during the Eocene time period and eventually traded in their arms to become “sleeker and more streamlined,” while still holding onto their teeth.
By now they look less like a wolf and more like a murderous dolphin.
You're welcome for the nightmare fuel.
Cut to roughly 34-36 million years ago, and the species have diversified into the two major whale groups we see today: the Odontoceti (or “toothed whales”), which include sperm whales, orcas and dolphins, and the Mysticeti, better known as baleen whales … you know, those big guys with the filter-like “teeth” (aka baleen) that eat loads and loads of plankton?
The baleen whale’s evolution in particular has scientists a bit baffled, as there is no definitive evidence as to how, when or even why they began filter feeding in the first place. In fact, the first fossil of a mysticetes appeared around 36 million years ago, but baleen doesn’t show up until later, around 11 million years ago. Even the baleen’s oldest ancestor, the Mystacadon, according to the PBS video, showed no signs of baleen when researchers discovered it in 2019.
One theory: The cooled ocean current of the Oligocene epoch brought about an abundance of nutrients—specifically plankton—which made it more advantageous to bulk feed rather than hunt for single prey. This also helps explain the giant boom in different whale species.
Still, it’s all up for debate, and likely will be for a while since ancient baleen is hard to come by. Baleen, unlike teeth, is made of keratin, the same biodegradable substance hair and nails are made out of and, therefore, doesn’t fossilize well.
As the host cleverly quipped, “It’s basically like a big mustache inside the whale's mouth.”
Bottom line: We know a lot about nature, but there is still so much to learn.

12 non-threatening leadership strategies for women
We mustn't hurt a man's feelings.
Men and the feels.
Note: This an excerpt is from Sarah Cooper's book, How to Be Successful Without Hurting Men's Feelings.
In this fast-paced business world, female leaders need to make sure they're not perceived as pushy, aggressive, or competent.
One way to do that is to alter your leadership style to account for the fragile male ego.
Should men accept powerful women and not feel threatened by them? Yes. Is that asking too much?
IS IT?
Sorry, I didn't mean to get aggressive there. Anyhoo, here are twelve non-threatening leadership strategies for women.
Encourage.

When setting a deadline, ask your coworker what he thinks of doing something, instead of just asking him to get it done. This makes him feel less like you're telling him what to do and more like you care about his opinions.
Sharing ideas.
With permission from Sarah Cooper.
When sharing your ideas, overconfidence is a killer. You don't want your male coworkers to think you're getting all uppity. Instead, downplay your ideas as just "thinking out loud," "throwing something out there," or sharing something "dumb," "random," or "crazy."
Email requests.
With permission from Sarah Cooper.
Pepper your emails with exclamation marks and emojis so you don't come across as too clear or direct. Your lack of efficient communication will make you seem more approachable.
Idea sharing.
With permission from Sarah Cooper.
If a male coworker steals your idea in a meeting, thank him for it. Give him kudos for how he explained your idea so clearly. And let's face it, no one might've ever heard it if he hadn't repeated it.
Sexism.
With permission from Sarah Cooper.
When you hear a sexist comment, the awkward laugh is key. Practice your awkward laugh at home, with your friends and family, and in the mirror. Make sure you sound truly delighted even as your soul is dying inside.
Mansplain.

Men love explaining things. But when he's explaining something and you already know that, it might be tempting to say, "I already know that." Instead, have him explain it to you over and over again. It will make him feel useful and will give you some time to think about how to avoid him in the future.
Mistakes.
With permission from Sarah Cooper.
Pointing out a mistake is always risky so it's important to always apologize for noticing the mistake and then make sure that no one thinks you're too sure about it. People will appreciate your "hey what do I know?!" sensibilities.
Promotions.
With permission from Sarah Cooper.
Asking your manager for a promotion could make you seem power- hungry, opportunistic, and transparent. Instead, ask a male coworker to vouch for you. Have your coworker tell your manager you'd be great for the role even though you don't really want it. This will make you more likely to actually get that promotion.
Rude.
With permission from Sarah Cooper.
Sometimes not everyone is properly introduced at the start of a meeting. Don't take it personally even if it happens to you all the time, and certainly don't stop the meeting from moving forward to introduce yourself. Sending a quick note afterward is the best way to introduce yourself without seeming too self-important.
Interruptions.
With permission from Sarah Cooper.
When you get interrupted, you might be tempted to just continue talking or even ask if you can finish what you were saying. This is treacherous territory. Instead, simply stop talking. The path of least resistance is silence.
Collaboration.
With permission from Sarah Cooper.
When collaborating with a man, type using only one finger. Skill and speed are very off-putting.
Disagreements.
With permission from Sarah Cooper.
When all else fails, wear a mustache so everyone sees you as more man-like. This will cancel out any need to change your leadership style. In fact, you may even get a quick promotion!
In conclusion...
With permission from Sarah Cooper.
Many women have discovered the secret power of non-threatening leadership. We call it a "secret power" because no one else actually knows about it. We keep our power hidden within ourselves so that it doesn't frighten and intimidate others. That's what makes us the true unsung heroes of the corporate world.
