Are we slaves to our genes, and is who we are already written in our DNA?
In this live edition of Unbelievable?, recorded at Aylesbury High School, Andy Kind is joined by humanist physicist Dr. Simon Walker-Samuel and Christian biologist Dr. Denis Alexander for a lively and thought-provoking debate on genetics, free will, and what makes us… us.
From CRISPR and epigenetics to moral responsibility, determinism, and the question of "the soul", this conversation dives deep into whether our genes define our destiny, or if there's more to the human story. Are we morally responsible if we’re biologically programmed? Can science detect a “soul”? What do twin studies reveal about nature vs nurture? And do your genes influence your beliefs?

Are we just highly evolved biological machines? Or is there something that transcends our biology?

The cost of keeping hope on air is soaring.

Transmission costs are rising, and Premier receives no government funding. To keep broadcasting hope, truth and encouragement across the UK, an essential funding gap of £579,200 must be filled. 

From 21st September on Premier Christian Radio, join with other listeners to keep faith-filled content on air - for the paramedic driving home after a difficult shift, for the widow in the quiet moments, and for the new believer seeking answers to life's questions. 

If you want to lead the way, you can get in early today.
