Do you know about epigenetics and genes that are switched off and on based on various factors throughout lifespan? The DNA sequence is relatively fixed, however the expression of these genes is highly malleable and responsive to the environmental and behavioural factors which is known in research now
one question. what if the light brown fur colour is caused by a recessive gene. Now we know recessive genes must be homozygous in order to manifest. How then do we say that the trait for brown colour will still be present when all dark mice are eliminated.
Why do we need to learn about Lemark if his theory of evolution has been unfounded? His theory was more a brain of matter concept!
We do not 🚫
My question too
I wish this video came out a day earlier because I did my gcse biology exam today and the last question was on this but I think I did alright
Oh no my sorry that it didn’t come out soon enough!
@@missangler it’s all good but thanks anyway still a good and helpful video
Thank you for your help mam. ❤️

Thanks miss angler
so....what about benafit (benefit)

always saving my grades...
Darwnism is based on an atheistic view, those who believe in a supreme being believe we were created by god
Ur just commenting to comment atp
@@idkwhattoputhere1636 lmaoooo, his right
Is protein synthesis coming up in the final paper
Probably just revise it just in case it does you can't be too sure 😊
does this mean that if we stretch our arms to get things from higher places, will our generations be taller?
No that’s Lamarckism, you can’t pass on a physical change via genes to your offspring.
