We are able to modify sections of DNA to change things, but this has previously been on on a relatively small scale – for simple creatures or simple characteristics. Changing whole sections of DNA to create an extinct animal is a big undertaking. It’s not being done right now, but who knows what the future will hold.
It’s a great question, and if I can speak to any geneticists before this competition is over I’ll try my best to get an answer!
