[GeorgeDCowley]

This was more in-depth than I could have put it, and I also learned some numbers.

[benwest]

I cannot breed successfully with humans. I guess I'm a different species

[joecocker]

This guy organized all my knowledge into posh words

[lukejohnson]

Hi, could you. Make a video where you go through some difficult biology exam questions?

[lilyparker]

Hey, I was wondering doesn't Darwins theory appear in combined due to its link to natural selection?

[AceOfSpades]

I dont get it How come you never mentioned anything about chance mutations???Pls reply

[JohnDoe-wyzj]

Would the gradual change in the eating, or hunting habits of an animal be considered evolution by natural selection?

I don't think it's a change in the inherited characteristics but even then it could be a result of adapting to the ever-changing environment, for instance climate change or the migration of other animals in an area.

So what is the definition of evolution as i got a bit confused which one it is and the aqa specification is very confusing? Oh and by the way thanks for your help.

But how does the rabbit spontaneously get the allele for thicker fur?

[lottie]

Thank you for your videos you are so so helpful! :)

[priya]

Is a rabbit chaning its features like its fur called evolving though natural selection?

[jessiegill]

hi sir, is everything you say in the videos worth making flash cards on?? for example- like how many different species there are in the uk. thank you
