A geneticist and internationally recognized anti-racism educator provides a powerful, science-based rebuttal to common fallacies about human difference. Well-meaning physicians, parents, and even scientists today often spread misinformation about what biology can and can't tell us about our bodies, minds, and identities. In this accessible, myth-busting book, geneticist Shoumita Dasgupta draws on the latest science to correct common misconceptions about how much of our social identities are actually based in genetics. Dasgupta weaves together history, current affairs, and cutting-edge science to break down how genetic concepts are misused and how we can approach scientific evidence in a socially responsible way. With a unifying and intersectional approach disentangling biology from bigotry, the book moves beyond race and gender to incorporate categories like sexual orientation, disability, and class. Where Biology Ends and Bias Begins is an invaluable, empowering resource for biologists, geneticists, science educators, and anyone working against bias in their community.
