A thought occured to me today after watching a short introductory video on epigenetics.

We all learned in high school that Lamarck hypothesised that traits were passed down according to use/disuse, "if your dad was a weightlifter then you'll get his muscles", but that this was disproven by natural selection. Now epigenetics from what I understood are genetic tags that can be changed over the life of an organism through its behavior or environment, altering how genes are expressed, and also that these tags can be inherited.

Does this mean Lamarck was at least partially right? Or am I misunderstanding something?
