Abstract

HBG2 subsequently became switched on specifically in the developing foetus, where ir ensures the high oxygen affinity of foetal blood for more efficient oxygen transfer across the placenta. [...] the important process of gas exchange in the womb has been significantly improved by jumping genes in higher primates, in contrast to many other mammals, including prosimians, where foetal and adult haemoglobins are the same.
