These Microbes Changed Evolutionary Biology Forever | Archaea and the Tree of Life

Dipti Nayak, Ph.D., explains how the mysterious #microbes known as archaea are helping scientists rewrite the tree of life.

Before 1977, all life on Earth was classified into two groups: single-celled microorganisms and complex cellular life such as fungi, plants, and animals. A seminal discovery in 1977 rewrote the tree of life and introduced a whole new domain of organisms known as the archaea - mysterious microbes that are genetically distinct from bacteria. Fast forward to the 21st century, and again new discoveries about archaea are leading scientists to reshape the tree of life and rewrite the evolutionary history of complex organisms. Nayak introduces the fascinating organisms known as archaea and explains how they are helping scientists answer the question "Where do we come from?".

Thank you to all who joined in for our Premiere! Would love to hear your thoughts below.

[blakedowning]

Dr. Nayak is my mentor, and such an inspiration to work with every day. I'm so glad she's getting to share all she knows about Archaea through iBiology! They're absolutely fascinating organisms.

[Sweercheff]

Great video. Amazing topic and awesome communicator. I sure hope Dr. Nayak is writing a book, since I'd love to read more about our incredible archaean ancestors.

The first video I watched in this channel was about spore formation some five years ago and since then have been visiting this channel and have subscribed to it. This is truly wonderful channel which office lectures from world's top scientists for free. Absolutely love your work. Keep it up.

[devinyoung]

Dr. Dipti, you are an excellent presenter. I hope you continue researching as well as presenting nuanced topics in biology!

[ssiddarth]

So damn interesting & the way Dipti explained everything was so good, Thank you 🤗

[sahastranshupandey]

Just Mind-blowing explanation by Dr. Nayak and just fascinating video editing. JUST LOVING IT!

[brucebentz]

Congratulations, you've really raised the bar on the iBiology videos. Excellent presentation, excellent artwork, it was a real pleasure to watch. I've enjoyed iBiology for years, this stands out as a real piece of art!

[afreenhaque]

Two domain sounds interesting....it's interesting. Thank you iBiology.

[virginiabartter]

Wow! I was looking for greater understanding of archaea because of methane bloom in my gut. Although this didn't really help me, it is SO interesting! So glad I ran across this very well articulated video! Thank you!

[Petrov]

Very timely and interesting -- thank you

[johnbaker]

Thank You Dipti !!
A fascinating topic and a lovely soul to introduce us, what more could we want?

[pankajkumar-hbqp]

It's valuable information for science students. I want more about it so please start more classes about evolutionary science. Thank you very much

[haeyba]

What an intriguing presentation! Makes me want to dive deeper into learning about the tree of life (": Thank you so much for imparting these information with us!

[plantlife]

I have waited over a week for this! Thank you YouTube algorithm.

[jrrando-ux]

I wish they could just teach like this in school! So easy to understand!

[robertab]

I recommend work: An excavate root for the eukaryote tree of life (2023).
It is possible that there was endosymbiosis of delta/gamma-proteobacteria before endosymbiosis of alpha-proteobacteria (ancestors of mitochondria).

[johnpalgrave]

Excellent explanation easily understood. Here beginneth our . ..

[lalaliri]

wonderful! Thank your for sharing this knowledge with us

[DrNem]

Such a fascinating talk, I would love to see more of this topic and origins of life!
