He mentioned the mechanical advantages of being symmetrical. But most importantly, if you have a front and back end(head, tail), it is easier for DNA to repeat instructions laterally on both sides of the bilateral line, because, during cell division, it will take much more energy and time to duplicate a longer DNA strand for a non symmetric organism without any errors. As long as DNA can label where the front and back are facing so that arms or legs are not placed backwards, cell growing patterns in embryology become more straightforward. For those reasons, it is an advantageous adaptation because energy conservation can be used towards other adaptations which means greater fitness. It is also important for the outer layer of an organism to be symmetrical along with teeth.

Having finished biology degree. Bilateral symmetry of mammals is generally external. Once you counted internal organs. The arrangement is not equal left and right.

The title should be the biology of symmetry.

Great video on symmetry

great video. learnt alot

Thanks I understood well 👍🏻

very nice animation!!!

4:40 the way u said "when reminds me of hot rod whiskey scene xD

nice explanation

I remember the episode of cyber chase where they talk about symmetry. You forgot about slide symmetry which mainly implies to long things like fences and combs

That fox is so damn hilarious haha

Genetics are even more important than symmetry in figuring out the tree of life. Similar phenotypic characteristics can pop up in separate places totally on their own. Symmetries are important to understand in phylogeny if there is some sort of discrepancy in genetic lineage, but it is supplementary information, more than anything else, in determining the tree of life. The beginning of the video veered off course into biology rather than sticking to a discussion of symmetries in all subjects, and made conclusions that, although correct, are not thoroughly discussed in respect to all other subjects.

amazing!!

The animations are so cute!

I like the idea. But how does the definition of symmetry work with bilateral symmetry ? Is it transformation of reflection or something ? Anyway the definition is new to me and it is intriguing too.

@jorgealexandre4616

The transformation is reflection in that case

My only issue here is that a lot of those rotationally symmetrical organisms that you said were less related, are also bilaterally symmetric.

Thank you

This is so adorable

The animation of this video is so nice! way better than mine :)

what is difference between radial and biradial symmetry ?

Well isnt this explanation wrong according to set theory since only rotation by 360 or 0 degrees is considered an identity under the triangle symmetry group.

may I suggest to read some Richard Dawkins' book to understand why we are bilateral and no, say, 90° rotational symmetric...; basically it's a matter of economy. it's better , as a fish, to differentiate a head from a tail (like they said in the video), it's good also to differentiate an top part from a bottom part (this simmetry is broken by gravity that pulls in the vertical direction) but there would be no gain in differentiating left from right... therefore evolution lead to an economy by having left and right look the same.

Symmetry is not only in biology but it is found in the whole universe. From an atom to the biggest galaxies, all have some kind of symmetry involved and if you are smart enough to visualize this then I am sure you will find symmetry everywhere. Physics is arguably all about symmetry!

Are you bilaterally symmetric if you missing an arm or for example have a deformed eye?

@cadman2300

Yes, because you still have the same ancestral genes and morphology that gave you your bilateral symmetry. And even if you were born with such deformities you're still the offspring of your respective group. That's taxonomy in a nutshell.

Remember that the bilateral symmetry is only approximate. Even if you have everything intact, you'll still have spots, scars or other features on one side of your body that aren't present on the other.

Thats an interesting accent!

Nice observation Sherlock...

All life on earth started in the oceans with an offset in gravitational pull from Spring Tides (FULL/DARK MOON) to Neap Tide (QUARTER MOONS) so it would of began there. ALL life on earth is related and came from shared ancestory in the ocean.

Raul Pinto symmetry arose before there were animals. It's perfectly normal for a species consisting of very few cells to do this. Once the genes were set up to be used multiple times, any change to it affected both sides. If it wasn't useful, it could disappear. If it was, it stayed. It's not ridiculous, you just don't seem to like it.
