Mammary glands in a bowl – what miniature organs reveal about evolution, breastfeeding, regeneration and breast cancer

All mammals have milk-producing mammary glands, a feature that has fascinated scientists for many years. Questions remain largely unanswered, including why mammary glands evolved in the first place, how they have adapted across species, and what unique evolutionary pressures shaped their development. To investigate how diverse species develop unique solutions to biological challenges, my team… Read More »
