" Much of the attention paid to CRISPR these days involves its potential to make inheritable (germline) edits in humans that will be passed along to all the cells of all of our future descendants and have the potential to alter our species. These edits are done in reproductive cells or early-stage embryos. This is what occurred with the CRISPR baby twins in China in 2018, and it is the controversial topic that I will discuss later in this book. "
