Why Do We Do That? An anthropologist's guide to the modern world.
There are lots of everyday things which, when you think about them, are pretty weird. Like kissing, doomscrolling and sitting down to go to the loo. Social media may tell you to blame the latest influencer who went viral. Your therapist might tell you to blame your parents. But palaeoanthropologist Ella Al-Shamahi is here to tell you to blame your great, great, great, great, great, etc. grandparents. For some stuff at least. In this series, Ella is joined by some wonderful guests to dive into the cultural, historical and evolutionary story of everyday human habits and behaviour.

Ella Al-Shamahi explores evolutionary mysteries in More Lies with Roman Stengelin. BBC Studios Audio Producer: Olivia Jani Additional Production: Emily Bird Series Producer: Geraldine Fitzgerald Executive Producer: Alexandra Feachem
Ella Al-Shamahi asks why do we lie? You might think that deception is a uniquely human characteristic, but does camouflage or mimicry in nature, where animals pretend to be another animal or the actual environment like the insects leaf-mimic katydids that walk around looking like a leaf. Does that count as lying? Or is it just us humans with our highly complex language that have the ability to tell a fib. Ella talks to Dr Roman Stengelin of the Max Planck Institute for Evolutionary Anthropology,...
BONUS: Ella Al-Shamahi explores evolutionary mysteries in More Laughs with Sophie Scott. BBC Studios Audio Producer: Olivia Jani Additional Production: Emily Bird Series Producer: Geraldine Fitzgerald Executive Producer: Alexandra Feachem
Ella Al-Shamahi asks why do we laugh? Some people might not have a sense of humour, you might even know someone who never laughs… but there isn’t a culture out there, say a tribe, where people just never laugh. It does appear to be universal but how universal and how primal? Many mammals and the great apes ( chimpanzees, gorillas and bononbos) laugh. Orangutans diverged from the other great apes including us about 12 million years ago and because we all laugh that suggests our shared common ance...
BONUS: Ella Al-Shamahi explores evolutionary mysteries in More Dogs with Greger Larson. BBC Studios Audio Producer: Olivia Jani Additional Production: Emily Bird Series Producer: Geraldine Fitzgerald Executive Producer: Alexandra Feachem
Ella Al-Shamahi asks why do we love dogs? Dogs evolved from wolves but why did they choose us humans to be their best friends? They say dogs are a man’s best friend but all dogs, even chihuahuas are descended from wolves, the grey wolf, a majestic, fierce and incredibly dangerous species. How did this happen but more importantly, why did we start trusting wolves? And when did wolves turn into dogs? Dogs have been a part of our story for a long time. They are depicted in cave and rock art and dog...
Ella Al-Shamahi explores evolutionary mysteries in More Grandmothers with Emily Emmott. BBC Studios Audio Producer: Olivia Jani Additional Production: Emily Bird Series Producer: Geraldine Fitzgerald Executive Producer: Alexandra Feachem
Grandmothers are a bit of a mystery, biologically speaking. If the biological purpose of life is to survive and have children, why are they so important even once they've stopped being able to reproduce? Of course, as we all know, grandma's are the rock of most families, and it turns out, biologically also incredibly useful. Grandmothers are a logical necessity, your mother and father also had mothers so that equals two grandmas for you. But the evolutionary role they play in many of our lives h...
Ella Al-Shamahi explores evolutionary mysteries in More Football Fanatics with Martha Newson. BBC Studios Audio Producer: Olivia Jani Additional Production: Emily Bird Series Producer: Geraldine Fitzgerald Executive Producer: Alexandra Feachem
Ella Al-Shamahi is joined by Crystal Palace superfan Bobby and psychologist Martha Newson to find out why it's so devastating when our football team loses. People who normally keep a stiff upper lip through life's ups and downs are distraught after a defeat. Is this a cultural response or something more primeval? Martha’s work shows that being beaten by another team deepens social bonds with fellow fans. From her results the fans of the least successful football clubs, including Crystal Palace, ...
BONUS: Ella Al-Shamahi explores evolutionary mysteries in More Gossip with Nicole Hagen Hess. BBC Studios Audio Producer: Olivia Jani Additional Production: Emily Bird Series Producer: Geraldine Fitzgerald Executive Producer: Alexandra Feachem
It can be the source of drama that ruins reputations or simply keeps you entertained during your lunch break. But is gossip ingrained in our nature? Anthropologist Ella Al-Shamahi digs into our evolutionary history to uncover the truth behind this age-old human habit. Joining her are Kelsey McKinney from the Normal Gossip podcast and anthropologist Dr. Nicole Hagen Hess, as they unravel the origins of this sometimes controversial behaviour. Could gossip be the social glue that binds us together,...
Ella Al-Shamahi is back to once again investigate the origins of everyday human habits and behaviour.
Are you drawn to the endless news cycle? Do you keep going back for more? Do you feel a strange compulsion to absorb negative news that is weirdly soothing but makes you more stressed? These are signs you may be doomscrolling. But fear not, you’re not the only one. Stuart Soroka is a professor at UCLA who’s been looking at our draw towards negative information and found that people all over the world do it, regardless of culture. In 2020, our year of misery, the Oxford English Dictionary added d...
It’s a familiar problem with any shared household - there’s always someone who doesn’t do their fair share. Studies have shown that when people with different thresholds live together, the person with the lower tolerance for mess cleans up more, quickly leading to resentment and conflict. So why do some people clean up more than others? What needs to happen for everyone to pull their weight? Evolutionary science has some answers. Ella Al-Shamahi speaks to Dr Nichola Raihani, Professor of Evoluti...
Make-up has a long history - from the surprising use of lipstick in ancient Greece to today's Tiktok trends - and though fashions may have changed, some things, like red lips, cheeks, and defined eyes, keep cropping up. So in this episode, Ella Al-Shamahi investigates if there is any biological basis to make-up? Joined by Journalist and BBC Radio 1 presenter Katie Thistleton, and psychologist Professor Richard Russell, Ella discovers fascinating research on how make-up can change the way we perc...
You might think sitting is a recent technological advancement, but both squat and sit-down toilets have been around for millennia. Today Westerners have embraced the sit-down toilet, whereas billions in Asia, the Middle East, Africa, and even parts of Europe use toilets that are designed specifically for squatting. But which is better for us - sitting or squatting? Ella Al-Shamahi speaks to gastroenterologist Dr Rohan Modi who has been investigating the best way to do your business, and gets per...
Are you at one with midnight, or up before sunrise? In this episode, Ella Al-Shamahi investigates when we naturally feel tired and awake, known as our chronotype. Our chronotype depends on our lifestyle, our environment, where we live, and is also influenced by our genes. In this episode, Ella Al-Shamahi uncovers fascinating research which suggests our chronotype can be traced back over 100,000 years ago, to when our early modern human ancestors interbred with Neanderthals. She speaks to genetic...
The handshake has been threatened several times throughout history. It was even made illegal in Prescott Arizona due to the Spanish Flu — and yet we keep returning to it. In this episode, Ella Al-Shamahi delves into a possible biological explanation for why we handshake. Studies have shown that we bring our hands close to our face after a handshake, and then subconsciously take a sniff (inhalation through the nostrils doubles). The human body emits over 2000 volatile compounds that change depend...
Procrastination is the thief of time - or so the old saying goes. Studies have shown that people who procrastinate have higher levels of stress and lower levels of well-being. So why do we do it? One theory is that focusing on the here-and-now was beneficial for our palaeolithic ancestors. Dr Caroline Schulter from Ruhr-Universität Bochum in Germany found that chronic procrastinators have a larger amygdala, a key area in the brain that processes and learns from emotions. Could it be a coping mec...
This episode is all about the iconic kiss. Is it as universal as we think? One study suggests that lip-to-lip romantic kissing - the snog, if you will - is only present in 46% of cultures around the world. So did we just recently learn to do it? Ella Al-Shamahi speaks to Journalist and Radio 1 Life Hacks Presenter Katie Thistleton to get deep into the strangeness of kissing. Speaking to Dr Rafael Wlodarski from Oxford University, they find out how kissing, or getting close to one another, has be...
Ella Al-Shamahi is joined by psychologist Prof Laurence Steinberg and DJ / presenter Arielle Free to explore why we are drawn to do things that are bad for us. If our evolutionary purpose is to survive long enough to pass on genes, why do we knowingly put our lives at risk? Ella delves into a theory called costly signalling which may explain why we do risky things when there are others watching – is it just a way of showing off good genes? Dr Laurence Steinberg, Professor of Psychology at Temple...
In this episode, Ella Al-Shamahi delves into the origins of a broken heart. Words or phrases that use ‘heart pain’ to describe emotional pain appear in many languages, suggesting it is present in many cultures. Studies show that looking at photos of ex-partners within six months of a break-up triggers the same areas of the brain as physical pain. And as odd as it sounds, just like with physical pain, painkillers can act on feelings of a broken heart. So why is it so painful? TV and Radio Present...
