Watching evolution can be pretty incredible. Just trying to understand what’s going on in the world around us can be strange, but so fascinating. However, evolution never sleeps; it seems it’s been happening with monkeys in front of our very eyes, and we didn’t even realize.

Capuchin Monkeys Have Been Using Stone Tools

For quite some time now, it seems that certain types of monkey have been using stone tools for various everyday activities. It has mostly been for food purposes, but scientists have tracked that the way these animals have been using these tools has changed over time.

They Have Done This For Generations

The start of this kind of development is thought to be around 3,000 years ago, when monkeys would use stones to hit a small object. They would also use a larger stone beneath as a kind of anvil for their activities. There was then a long period where it seems as if primates stopped using this tactic, however, it got picked up a while later or rediscovered. About 257 years ago, it seemed as if monkeys were using heavier stones and bigger rocks as anvils to get into harder foods.

Humans Had Been In The Area

What researchers found interesting was that humans had also been in the area, making it hard to know whether the animals picked the idea of using stone tools from them, or whether it was the other way round. Three years ago it was discovered that Capuchin monkeys had picked this up, but that their ancestors had been doing it for some time now. It turns out that they’re not the only monkeys that do this and that various other monkey species also do this.

We wonder what the next development will be.

Before nabbing his main role on HIMYM, Josh Radnor had several guest spots on popular television series like 6 Feet Under and Law and Order. But it is easily his part as Ted Mosby, a guy looking for love in the big city, that people fell in love with.

Following his exploits through New York City as he searched for his love, you got to know all his friends as well. Josh played the role of Ted from the very beginning of the show until its end in 2014.

After the show ended, Radnor moved on to a leading role on a PBS show called Mercy Street. Josh was able to showcase his talents when he played the part of Dr. Jedediah Foster. The series ran for a year and had a total of 12 episodes.

After that, he also nabbed more main roles on TV series like Rise and Hunter. He also guest-starred on ABC’s beloved drama, Grey’s Anatomy. On top of being a great actor, Josh is also an author, singer, and director. Talk about someone who wears many hats!

Alyson Hannigan was already well known for her stint on the iconic supernatural teen drama Buffy the Vampire Slayer, as well as her role in the American Pie films. But her popularity significantly increased when she got the role of Lily Aldrin on HIMYM. 

As part of one of the most popular couples on the show, Alyson played a kindergarten teacher and art consultant married to one of Ted Mosby’s best friends.

After the show wrapped, Alyson went on to do several projects, including hosting the Girl Scout Cookie Championship and Penn and Teller: Fool Us. The actress has also collaborated with Disney.

Starring as Kim Possible’s mom in the live-action Kim Possible movie and she is also working on Disney Junior’s Fancy Nancy Clancy, voicing the lead role of Claire Clancy. She has also guest-starred on a couple of shows, including Pure and Outmatched.

Though you never saw him on the show, Bob Saget played a very important role in the show itself. Saget was the voice of Ted Mosby as he narrated through the show’s story. But Saget already had a pretty prominent career before earning this voiceover gig.

While working on the show, Bob also played roles on other television shows, including playing himself and the popular show Entourage. He’s not just an actor but also a stand-up comedian, host, and director.

After the show ended, he would try his hand at several different television shows and have guest-starring roles playing himself. But his biggest role since has been playing the reprisal of Danny Tanner on Fuller House.

Unfortunately, the show was canceled in 2020. However, he is currently working on a film called Killing Daniel and has been announced to be in another upcoming movie called Blue Iguana.

Jason Segel already had some serious success under his belt when he nabbed the role of Marshall Erickson on How I Met Your Mother. He had starred in both Freaks and Geeks as well as Undeclared.

As the other half of the show’s ‘it couple’, Segel played Ted Mosby’s good friend and former college roommate. His character was a corporate lawyer. Throughout the series, Siegel also starred in a couple of different films, including The Muppets.

Jason Segel had a pretty steady career while on the show. Since HIMYM ended, he has been seen less on this big screen as well as the small screen. However, he has had a few movie roles, such as in The End of the Tour and The Discovery. 

He also starred in a series on AMC in 2020 called Dispatches From Elsewhere. He not only wrote and directed the show but also created and executive produced.

Before becoming one of the stars of this iconic sitcom, Cobie Smulders had several small roles on television shows but had not quite found her groove yet. However, that would all change when she got the part of Robin Scherbatsky on the show.

Her character was a TV journalist who was strong-willed and hilarious. While doing the show, she had a small role in one of the Marvel movies that would later turn into a much larger one.

After the show had ended, Cobie continued to reprise her role as Agent Maria Hill in several of the Avenger films. The character also appeared in Spider-man: Far From Home. But that wasn’t the only role she nabbed.

Back on television, she had roles in both Arrested Development as well as A Series Unfortunate Events. She also starred in both Friends From College and the ABC show Stumptown.

Wayne Brady is a super talented actor, singer, and comedian who had already made a name for himself before HIMYM on shows like Girlfriends, Everybody hates Chris, and Whose Line is it Anyway?.

His stint on the show as Barney’s older brother was quite memorable, though. The actor appeared in this role in more than a dozen episodes, and while doing this, he was also working on several other projects.

Brady continues to work hard and has earned roles on the daytime drama The Bold and Beautiful, Real Husbands of Hollywood, and continues to work on Whose Line Is It Anyway?. On top of that, he was also the host of Let’s Make a Deal and Game of Talents.

He also guest-starred on shows like Black Lightning. As if his resume isn’t impressive enough, he also starred on Broadway and was a contestant on The Masked Singer.

It took some seasons before the character Tracy McConnell, who is played by Cristin Milioti, was ever revealed. Though it did take a long time for the answer that the series title poses for diehard fans, it was well worth the wait.

Like many of the other members of the cast, Cristin had had small parts on several shows before this role. But having a role in such a prominent series certainly helped her create a name for herself in the industry.

After the show ended, Cristin continued to find roles on several major television shows. Not only did she play a pivotal role in Fargo, but she also had roles on the TV series A to Z, as well as The Mindy Project.

Currently, she is working on the TV series Made for Love, playing the role of Hazel Green. On top of her TV work, she also starred in movies such as It Had to Be You and the critically acclaimed Palm Springs.

Ashley Williams began playing her role in the very first season but took a little bit of a break and didn’t return until the seventh season in 2012. As one of the potential contenders for who could be the mom, she played Vic, Ted’s on-again, off-again girlfriend.

The actress appeared in 16 episodes, and while taking a break, she also played Jeannie Gaffigan on The Jim Gaffigan Show for one season.

Since the show ended, Ashley has had several roles in Hallmark movies and small parts in a few television series. This includes shows like The Good Doctor and FBI. But where she is most seen is in holiday movies, such as Christmas in the City. 

In fact, in 2020, she appeared in two and is currently filming a two-part Christmas movie for the Hallmark Channel. We bet Mrs. Williams loves the holiday season!

Sarah Chalke had already starred in shows such as Scrubs, Roseanne, and Mad Love before she took on the role of Stella Zinman on How I Met Your Mother. In seasons three and four, the actress played Ted Mosby’s girlfriend.

While working on this show, she also was working on Scrubs and did a few episodes of Roseanne in 2018. This actress sure knew how to multitask! And she has another job waiting for her in the wings which may surprise some of you…

From 2013 until now, Sarah has voiced the part of Beth Smith on the highly-praised adult animated science-fiction series Rick and Morty. And if that’s not impressive enough, she also starred in movies like Mother’s Day and The Wrong Missy.

When it comes to TV, she has also had roles in shows like Cougar Town, Paradise PD, Friends From College as well as the Netflix show Firefly Lane in 2021.

Neil Patrick Harris had disappeared from television screens years after starring in his hit series Doogie Howser MD. Though he had been prominent on the stage until he earned the role of Barney Stinson on HIMYM, he had seemingly fallen out of the limelight.

Barney may well have been the most popular character on the show – a ladies man who likes to dress nicely and live the single life, Barney was the perfect image of the perpetual bachelor.

Neil continued to find work in Hollywood, scoring roles in major movies such as Gone Girl and A Million Ways to Die in the West. He also maintained his stage career and was involved in several different Broadway shows.

When it comes to TV, not only did he have a role in American Horror Story in 2015, but he also played Count Olaf and the TV version of A Series of Unfortunate Events, which he also produced.

In season seven, Barney happens to meet a stripper with whom he begins a relationship and eventually asks to marry her. Of course, in the end, Barney doesn’t actually get married, but even still, Becki Newton was able to nab quite a role on one of the most popular shows.

The actress had already had quite a bit of success starring in the very popular TV series as Amanda Tanen, the attractive receptionist on Ugly Betty from 2006 to 2010.

Once her stint on How I Met Your Mother was over, Becky picked up roles on both TV shows and a few movies. She also continued to voice several characters in American Dad!. TV-wise, she had roles on shows such as The Goodwin Games and Divorce.

Her film work includes having roles in movies like Otherhood and Winning Ugly. However, she hasn’t been particularly busy since 2019. Here’s to hoping that Ugly Betty gets a reboot!

Alexis Denisof was well known for his roles on both Buffy the Vampire Slayer as well as Angel before landing the role of Sandy Rivers on How I Met Your Mother. Playing opposite of Cobie Smulders, he may not have been a pivotal character, but he sure was funny.

His character would appear on and off again throughout the entire series run, and while he was playing this role, he also had roles on the TV show Dollhouse and Grimm.

After the show, Alexis went on to star in several television shows. Shows like MTV’s Finding Carter and Netflix’s Chilling Adventures of Sabrina have kept the actor very busy for the last six years.

Most recently, he has been playing Rupert Vardemus on CW’s Legacies. It seems to us that he may have a little thing for vampires! What do you think?

One of the most important jobs in New York is, of course, the cab driver. Marshall Manesh played a small but important role as the constantly hailed cab driver Ranjit on the very popular sitcom.

This character was seen quite often as he seemed to be the only taxi driver to drive the group of friends around the Big Apple. During his time on the show, he also did several other shows and movies, keeping busy when not driving the gang around.

After playing the fan-favorite cab driver on the show, the actor went on to work more on television. He found himself in recurring roles on shows like The Brink and Cooper Barrett’s Guide to Surviving Life as well as Good Girls and Madam Secretary.

He also found his way into roles in films, including The Last Conception and Tiger. The last credit on his resume is a movie called Playing with Stars, which was released in early 2021.

Of course, the whole premise of the show was Ted Mosby telling the story of how he met his children’s mother. So, you would have to have the kids too. Lyndsy Fonseca played his daughter Penny who was seen on several occasions.

The actress had already had a long run of very successful roles on television, including on series like Big Love and Desperate Housewives. She also acted in movies like Kick-Ass and Hot Tub Time Machine.

After playing the vital role of Penny in the show, the actress continued her run on television with roles in Marvel’s Agent Carter and RePlay. She also made guest appearances on 911: Lone Star.

Her most recent project is the Turner and Hooch television show which is now in post-production. We can’t wait to see what other roles this talented actress will nab in the future.

David Henrie had honed his skills as one of the many talents on the Disney Channel. He had coveted roles in shows like That’s So Raven and his most well-known one being none other than Wizards of Waverly Place.

On HIMY, David played Luke Mosby, the younger brother to Penny, who is being told the story by his father, Ted Mosby. Like Penny, he was seen several times during the series and, of course, was a super important plot point to the continuation of the series.

After the show ended, David continued to work on both television and movie screens. In 2016 the young actor took a break for a couple of years. But he came back to the screen in 2020 when he starred in the comedy This Is the Year. 

The young actor is currently filming a movie about the United States President Ronald Reagan where he plays a young Reagan. The movie’s release date is unknown. But we are really looking forward to seeing his performance in the role.
