Macken Murphy is a social scientist who studies human relationships and evolutionary anthropology. He holds degrees from Boston University and the University of Oxford and is currently a PhD researcher at the University of Melbourne. Murphy is known for his science-based analysis of romantic relationships, which he shares through videos and social media, amassing over 460,000 followers and 35 million views in the past year. He also hosts "Species," a podcast on evolutionary biology recommended by Apple and BBC's Wildlife magazine.
Beyond his online presence, Murphy is also a writer. He co-authored the children's book "Animal Sidekicks: Amazing Stories of Symbiosis in Animals and Plants" in 2022. In late 2025, William Collins pre-empted Murphy's study of "lasting love" in a six-figure deal; the book is scheduled for release in Spring 2028 and will explore the science of monogamy. Murphy aims to provide an optimistic perspective on modern relationships, countering misogyny and misinformation often found in relationship advice.
