You will have to learn how to reply. At the moment, nobody can tell what you’re replying to because there is no indication. You can quote by highlighting a section and clicking on the quote button that appears. Or you can hit the little gray “Reply” to the bottom right of the post you want to reply to. (Don’t confuse it with the green “Repy” at the bottom of the page.) Either will produce a reference back to the original post.
If you were replying to me, the idea of cultural evolution being non-genetic is hardly Lamarckian, and it has nothing to do with anyone’s views of biological evolution. I don’t see the point of bringing it up in a thread on the subject in the title.
