Watch the Deep Time Hall livestream here: You can set a reminder on that post to be notified when it goes live! Don’t forget to check out When Whales Walked: Journeys in Deep Time: As a scientific concept, evolution was revolutionary when it was first introduced. With the help of all three of our hosts and the Smithsonian National Museum of Natural History’s new Deep Time Hall, we’ll try to explain how evolution actually works and how we came to understand it.

Ray Costa : I just freaking love this channel, goddam

Sankshay Macha : Could you please do a video on australia's megafauna like the megalania and marsupial lion.

LilleWilleKille : The jumping back and fort between the different hosts was genius! I love it! Do this more please!!

Danquebec01 : 1:14 I’m so happy Wallace is getting recognized together with Darwin for the theory of evolution.

Dr.Bright : Evolutionary biology is beautiful. The fact that I'm distantly related to my dog, the grilled mushrooms I just ate, and the tree in my front yard is amazing.

Wan Lee : Marvel: infinity war will be the most ambitious crossover of all time... PBS Eons:

get out : I’m addicted to these videos...

Nashay Jones : This was awesome! I don’t think I ever realized that Mendel was a contemporary of Darwin and Wallace.

Dhindara Vrel : Don't forget Humboldt's influence on Darwin's thinking - it was Humboldt's development of the science of ecology that helped Darwin understand how different lifeforms influenced one another.

Михаил К : so much respect here, for science and the people driving it forward — it really warms my heart) thank you! this Darwin quote in a museum, that's so beautiful)

Moose Crone : Wow, Okay. Wasn't expecting to see a review of my whole first year of college biology. Great video!

Odin Sutherland : I just have to ask for an episode on monotreme evolution, and to thank you guys for revitalizing my love of Paleontology, you have given me something to work towards for my future, and I can thank you enough

Christopher Madeira : Could you make more videos on prehistoric oceans?

marim0y : This is a very well scripted episode. Can't wait to see the follow up at the Smithsonian. 💙

Dorvuzak Uzn : "The Hall of Extinct Monsters" sounds pretty damn cool tho.

Benjamin Mairs : This series is an orgy of knowledge, a celebration of science at it's finest. This is what I live for.

Tom Critter : I want more lbs ions. You guys should upload more often.

Veggieboy Ultimate : Wait, “When whales walked”?, that is one of your video’s titles! What a coincidence

mode prince : I really would like to translate that to Arabic .. as we need this in Arabic.

shohipa : Love the channel. Thanks Kellie, Blake, Hank and of course Steve. 😁👍🏻

krzyktty101 : This is one of my favorite videos so far. I love how you all participated in it together.

Darth Bane : This channel really is top notch. Very likeable presenters. The pacing, scripts and editing are pleasant. I wish i could double like.

HebaruSan : "It's a boy! What do you want to name him?" " 'Sewall'. " "..."

loogaan koolsen : A sponsorship by smithsonian (idk if I spelled it right) was unexpected

Rey Villa : From protoplasm to nerdgasm Eons4evah 😁 heh

Thishan Wijesinghe : "Charles Darwin and Alfred Russel Wallace..." BOTH HAD EPIC BEARDS!!!

Francis Srečko Fabian : I'm glad there is a move to include Wallace in the Theory Of Evolution. He deserves to be remembered. Rosalind Franklin deserves to be remembered. Without her work would Crick & Watson have figured out the structure of DNA? (I dunno, I'm not a biologist but I'm pretty sure her efforts should be noted). And someone named Maurice Wilkins who I didn't know about probably deserves some recognition too.

E S : congrats to david koch for the tax break. glad the exhibit exists, just wish *anyone else* had funded it, oof

VINOS : I always thought evolving was this cool shiny transformation with an epic soundtrack in the background

Burniture : In less than 200 years, scientific study has completely revolutionized our understanding of the constantly changing nature... of spacetime

Thomas Bowers : "I don't understand evolution and I have to protect my kids from understanding it. WE WILL NOT GIVE IN TO THE THINKERS ! " - Futurama :D

Gonzalo Suarez : so are you saying is not by grinding XP that animals evolve? damn all my life I have been wrong, blame on you pokémon

Benny Malone : Great video, thanks! Could you please do one on how the continents formed and shifted and which animals were around at the time in parallel. Thanks!

Matheus Castello : this video (and the new zelda announcement) made my day, thanks :)

Family Dog : As a biologist myself and someone who got interested evolution theory back in a school days, what a great video. Saved it to my playlist.

Hydris366 : I’ve always wanted to know this! Thanks PBS Eons!!!

Michael McInnes : Love the ensemble host video! Great way to present this!

Kevin Leleu : 4:36 Haha I see what you did there. Smooth.

Douggernaut84 : MARINE SLOTHS, MARINE SLOTHS! Plz do an episode with the marine sloths.

Amelia Hess : This was beautifully done :D

András Agócs : Damn, I wish I could go to the Smithsonian at some time in my life. :’(

Daniel Schmitt : Thank you for making this. I've tried explaining this to so many people.

stopscammingman : David H. Koch? Fitting, he's big on causing extinction!

Willem Bester : This is one of the few channels that always remains awesome. Thank you for hard and excellent work.

Vita Victoria : A topic so important it needs all three hosts to chip in. Brilliant!

Steven Chong - Creative Corner : How did Pinnipeds evolve when they broke off from other Carnivora?

Patrick Silerio : That's how evolution works.

finalmage6 : Really cool and unique video this week! Loved how all three hosts were involved even if it's just camera magic 😉

Maira Mattos : Congratulations!!! Greetings from Brazil!!🇧🇷🇧🇷
