Medicine and science have advanced majorly since Roe vs Wade in 1973. This includes tremendous advancements in ultrasound, foetal diagnosis, and the ability to do in-utero procedures. Ultrasound in 1973 was unable to clearly define the features of an unborn baby. Modern day ultrasound has made it possible to identify physical features and behaviours of the foetus including yawning, hiccups, thumb sucking and even right or left hand dominance. “Modern developments in our understanding of the humanity of the unborn are anything but ‘slim.’ If you follow the science, it’s clear that unborn children at 15 weeks’ gestation are already amazingly complex human beings”. Justices Breyer, Sotomayor, and Kagan incorrectly described modern developments in our scientific understanding of unborn babies as “slim” in their dissent to the Supreme Court’s decision to reverse Roe v. Wade.
