Natural Selection

- This video looks at the mechanism of natural selection and how it plays a role in evolution. We take a look at the Lamarckism and Darwinism and how they each would have explained evolution. An example of how natural selection could take place is used to help students understand what it would look like in a real world example.

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!
Thank you for your help mam. ❤️
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
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.
so....what about benafit (benefit)
Is protein synthesis coming up in the final paper
Probably just revise it just in case it does you can't be too sure 😊
always saving my grades...
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.
