I want to evolve into something else. I want my kids to be able to fly. How can I force a change in my genetics by myself to enable the first stages of wings and feathers to be included in my children when I reproduce. The thing is I don't want to use any laboratories or unnatural processes.

If evolution did it without laboratories and genetic engineering, surely there is a way for me to deliberately direct these mutations in a positive way by myself.

Thanks for your help in this.
