I love all of the explanations from this channel, easy to understand and very detail!!

[shayar]

The only video on the topic which has cleared my doubts.... subscribed 😄

[carriefu]

So well explained and ilustrated!! Thank you, BogoBio!!! 🤓💕

[tynyshasmith]

Amazing video! Will certainly help me for my Ap biology quiz tmr!

[cartoonwithw....]

One of the best and well explained video 👍🏻

[shazwena]

Thanks for Indonesian subtitle, it's helping much ❤

When is your next video.... Your videos help me a lot in my studies....'ll be waiting for your next vid

this makes me think about how I hear so many people talk about not wanting kids because of generational trauma /cycles and having to break those before having kids. these convos I had lead back to also violence we experience in the world now which lead me to think there are more people out there around the world feeling this, in a way that's breaking the cycle and delays a population what kind of effect will it cause? a lot of us are dealing with mental illnesses and fear it being passed down so don't have kids because of the experiences we had is that a type of selection?

Off topic maybe but what about gene regulation? surely genes get regulated differently in individuals depending on how much they're used. Which could slightly affect the next generations like with the regulation of melanin production.

Hey guys, can you please tell me that how do you make these tyPes of videos 🤗

[Sun-God]

How many years can a species/genus live without becoming another species or another genus? For example, can a species survive thousands or even millions of years without significant change and without becoming another species?

Can somebody explain this for me?

BUT WHATS THE DIFFERENCE BETWEEN ADAPTATION AND EVOLUTION? did it adapt or did it evolve

[CVskills]

I’m sorry but that’s not true..You have many mistakes in this video, how can I contact you to discuss them?!

This is literally the copy paste of class 12th biology chapter "evolution" in India😃

FACT ALERT. The theory is great but the math doesn't work. The randomness of selection occurs at the DNA Base Pair which codes for an amino acid as part of a long sequenced chain of amino acids. These chains are then folded with the assistance of another enzyme (protein chain) into functional shapes with water loving spots and water hating spots. The folded globules then do a function in the scheme of the life of the cell. Most mutations are irrelevant or harmful. The entire process is random, then selection acts on the whole organism, the organism with many features, some good, some not so good. Maybe it screws its way into the next generation and gene pool, maybe not. Either way, It takes more than 500 million years, JACK. Imagine that.

Climate change I can't stand this BS

Thanks for the video, I'll save it.👍

wow...turn that volume down a bit...you seem angry....like what natural selection does weeding out the bad stuff. We don't want it.
