New Time Travel Rule Idea

I just thought of this while on the toilet earlier. I’m not sure if this is already an existing time travel rule but here it is.

Your time travel powers come from your genes. You can time travel through your bloodline

Let’s say you’re a 21 year old who was born in a third world country that’s most likely been colonized. You wanna time travel back 10 years ago, you will get transported to your 11 year old body but keep your memories. You time travel back 100 years ago, you will get transported to your grandfather’s body from 100 years ago. You time travel back 1000 years ago, you will get transported to a European boy’s body who is your ancestor before your country got colonized. You time travel back 100,000 years ago you become an ape. You time travel back a couple million years back and you become a weird mammal. Go back a few billion years and you become the fish we once were.

All those bodies you become during your time travel has your same genes and they are all apart of your family tree.

If you travel to the future you gotta have a kid. But let’s say you don’t have a kid but you have a sister who also has the time genes, she becomes a mother. And now you can travel to the future through her kid’s body.
