The Seventh Son, Sebastian Faulks.

Who are we? Where did we come from? Neanderthal + Sapiens? Set 50 years in the future — Australia, Germany, the UK and US — Faulks, author of the acclaimed Birdsong, explores what may have happened  thousands of ages past, and did it lead to who we are today. AI, genetic engineering, test tube babies. Told through a doctoral student who becomes a surrogate mother, the couple who pay her, the son who is conceived. . . and unscrupulous scientists. Riveting.
