I really like this guys passion. You can tell he's overcoming nerves in this talk. The hidden ultraviolet flower patterns were pretty damn awesome, I'd love to see more of those!

i love the guys presentation. so genuine.

He's intelligent and very passionate! I'm glad he loves what he does.

Fascinating stuff. Jonathan Drori is a wonderful speaker. His love of the subject is obvious, and contageous.

This was amazing, he is totally emersed in this world. I love it!

Flowers makes everything beautiful 🌹🌷❤️

We are from Brazil and we would like to congratulate this brillant scientist! thaks for this!

What a treat! I want more!

Amazing!! Thanks for sharing.

Some truly amazing designs.

beautiful!

What a brilliant mind.

Beautiful

Beautifull! Good!

fantastic talk

I enjoyed this talk.

Great talk.

WAW, Excellents! Videos!

Very enjoyable talk !

great talk :D very interesting to know a bit more about how the evolution has played with diffrent beings

Amazing presentation

Awesome!

great talk!

I love this guy

lovely

great piece of information

mashallah ............Brilliant man ....awesome research........and yes very genuine presentation

He was very nervous at first... but a minute in he became a professor / teacher. He sounds like he talks to young people for a living. Always a good thing.

I really enjoyed that

Very informative and highly enjoyable. Amazing what a no brain plant can make us highly intelligent replicators do.

Really slow start but once he started geeking out he became mesmerizing.

This is the ultimate "flowers and bees" talk:)

"...every home should have an electron scanning microscope..." couldn`t agree more

great ending!!

very cool

great talk man :D

@reafdaw01 I think it is rather easily understood, once you understand that the factor driving the selection of the mimic isn't the other flower, but the insect that is symbiotic with the other flower.

@foot1647 totally agree! The intro is too loud in comparision to the rest of the video.

Plants are dominating the meta right now freaking Hyper Librarian dam

A-mazing

I'v never so interested in flowers as I just was watching that

givin the fact that people have had complaints about the intro being "too loud" for what seems like months now, at the top of the page with 100's of thumbs up, OBVIOUSLY TED doesn't read this shit or they just don't care, so please stop complaining about the damn intro so we can have something more amusing/funny/interesting to read at the top of the comments page, thanks and have a nice day :)

nice

homie brought out the big guns with them jokes

@foot1647 yup n also reduce the length of the tedtalks intro to 2 secs max pls?

What i liked the most about this presentation was the light filtering. The other stuff is common knowledge to anyone who has had biology in school (and payed some level of attention). As an analytical person, i have used similar techniques for light, sound, and data to look at it from a non-native perspective. Wavelenght shift and compression can bring out interresting things.

@TheHickstead Ohh yeaaahhhh!

ait how do the plants know at the insects look like

@kusotarre Yes but I think there is a big difference between understanding the mechanism and actually knowing how it evolved and what the involved steps were. Orchids which mimik insects and don't offer reward for example. How did they evolve? Were they pollinated by these same insects, offered them reward and then stopped it? Or were they pollinated by something different and changed their morphology drastically over only one generation (maybe because it is controled by a singel gene)?

@spinynorman1982 did she at least get you nectared up before she got you to take her pollen?

how do plants mimic other plants or animals ? how are they able to see, and then mimic it ?

0:40 - 0:45 MAD AWKWARD!...hahahah

Lol...awkward silence @:45. Great talk though.

6:29 anyone knows what plant that is?

flowers are the bee's knees (giggle)

Ah, the evening primrose. I read about it in Dawkins' The Greatest Show on Earth, I recommend it to everyone. Aside from being a beautiful display of life, it's a satisfying rebuttal to those who still don't think evolution is a fact.

@memoryhero feel the love

11:50 Damn he pointed at the loading bar and pointed out it was red.

How do flowers mimick what the insects look like? If they don't have eyes ...

@pixelbind It's better to say "I have some nectar would you help me spread some pollen?" I'll be trying that one out.

@foot1647 You should try the older ted videos. They've actually already reduced the sound of the intro's a while back :D

@brucebannerization That's very interesting cause I've always thought about that issue. I'm glad you've settled it for me though. Gotta love science right?

@TheHickstead You're absolutely right. Not first.

@lazyd0g considering how simple the concept of evolution is, it's weired that so many people don't get it. thx for not getting tired of repeating it over and over again.

@ratholin hehe^^

@yourtube20061 Natural selection does the job, plants cannot see. Reproductive success is a really important factor, and effective use of resources is another one. Plants are not conscious, its natural selection that shapes them. Its the eyes of the insects that choose which flower will be more successful at pollination and which one will be less successful. You could say the pollinators are "selectively breeding" the flowers. Also be aware that pollinators and plants evolved together.

7:31 lol, "designed..ehh ehm..evolved"

@doGoNsIylbaborPerehT brilliant description of natural selection.

wow wtf...that one plant basically evolved to become a kinky love shack for beetles. Awesome.

@doGoNsIylbaborPerehT i feel worth clarifying that Natural Selection is the non-random part of evolution, while mutation is random. This gives a random pool of possibilities, where the benificial ones to reproduction are selected, those neutral to reproduction may or may not be selected, and those hurtfull to reproduction are not selected.

@brucebannerization Why does having a common ancestor mean we all perceive colors the same?

"it's designed.. er.. evolved to" lol

@TheHickstead Spirit of youtube

How the hell do plants, which have no eyes or consciousness, know how to mimic insects? That's what I want to know.

@lordmetroid point taken funny thought though

I think i just learned a new way to pick up women. By identifying the flower that makes up their perfume A bit nerdy but that's who I am :D

Who knew plants were so raunchy

@DeePhlat Yeah, I know. I just thought it was funny how he corrected himself.

@papatoony evolution

@Dreamrio You are absolutely correct. That, however, is simply evolution. No one creature is able to adapt its future generation in a way it would think beneficial.

@qttytn No, silly. He is simply anxious.

@martynwonder There's different kinds of knowing - the concept of instinct, the genetic imprint; and the active process of learning something. Of course plants don't exactly have a brain, so active knowing is impossible to them. On the other hand, whatever is written in the plant's genetic code is something the plant knows how to do, whether it be growing a certain way, dying in a certain way, or mimicking something after millions of years of mutation alongside said something.

@yourtube20061 They can't see other plants. Plants that happen to mimik other plants have a greater chance of survival and will therefore spread. THe evolutionary process is quite complicated and often not understood.

This dude is like the Barry White of the flower kingdom.

great talk. serious business. i wanna buy a scanning electron microscope.

@warlord1981nl It's about plant sex. Pretty interesting stuff.

@ratholin nope! lol

@doGoNsIylbaborPerehT Thinking about it I should have known that lol But yeah this stuff intrigues me so thank you :)

@TheHickstead It doesn't matter where the video is from really.

Very sneaky plants.

@ghostdk Yeah, because otherwise creationists might quote mine him.

This guy is cool, lol.

@spinynorman1982 XD

@VideoNewZ9 Nay, a spermatozoa is different from a pollen.

@brucebannerization But couldn't it have mutated causing altered perception in different individuals? True that human DNA doesn't vary much but it varies enough to give us different races doesn't it? Also our minds and how they perceive things vary tremendously. Could color perception simply be another variation in the way our mind perceives things?

randomly evolving into an insect is impossible, don't believe me? calculate the possibility :P

@doGoNsIylbaborPerehT Just like a Heike Crab has no idea it looks like a samurai.

Is mimic the right word to use in these situations ? like The plant mimics an animal..... This is one of the things about evolution that i dont understand that well,because ppl, and even biologists use the word mimic , as if the plant knows that it's doing. As if the plant knows the reason for its sucsess is because it is mimicing some animal. what do you think?

lol why do people get so mad about people saying first

@martynwonder I think a plant can perfectly well mimic an animal without knowing it. The concept of plants knowing what they're doing is as far as I know a way of simplifying evolution, and should be ignored when trying to understand what actually happens.
