hi everyone

im stuck on this question if someone could give me some pointers id more than appreciate it.

Why is Darwin's Theory accepted and Lamarck's Theory not accepted Give Reason to Justify your response

i know that Lamarck's theory doesn't make sense but i need to justify why could someone give me some pointers id really appreciate it Thanks

Well Darwin's theory was simply "survival of the fittest" right? So those who adapted to their surrounding environments survived, and lived to produce the next generation. In effect, they mutated to change.
Lamarck's theory instead talked about how the individuals of each generation adapted and then passed these adaptations down to their offspring. Just quickly searching a bit more on Wikipedia shows that it's called "soft-inheritance".

Also, isn't Mendel's theory of genetics the one that is accepted? Since Darwinism is basically obsolete due to nothing about the genetical make up?

edit: huh, i didn't even really answer your question properly. Whoops...

edit edit: "After publication of Charles Darwin's theory of natural selection, the importance of individual efforts in the generation of adaptation was considerably diminished."

Darwin's theory of evolution states that species change over a long period of time. Basically through the concept of 'survival of the fittest' or also known as natural selection.

Lamarck's theory suggests use and disuse. That is, if for example, an animal didn't use a third arm, the next generation would not have the third arm. What's used is passed to the offspring and what isn't used is not.

Darwin's theory is more accepted. Lamarck's is not because well, I'm guessing there are some animals out there that have certain characteristics that are not used and still passed onto the offspring. However, to me it's just logical that Lamarck's theory is rejected.. don't know how to justify it unless I knew examples of those animals.

Darwin's theory however is accepted because of fossil evidence and heaps of other stuff.

I know this from year 12 biology btw so I'm not sure what you need for the school certificate.
