Species Unite
I think you could probably go back and track the stages of grief, probably that is what I went through. But I think if you do it right, you end up at acceptance. And that's where I ended up. And that's not to say that I've fully accepted the idea that the golden toad is extinct. Personally, I do still hold out hope that it could still be out there in those forests." - Trevor Ritland This conversation is with Trevor Ritland, who—along with his twin brother Kyle—authored The Golden Toad . The book chronicles their remarkable journey into Costa Rica’s cloud forest, once home to hundreds of brilliant golden toads that would emerge for just a few weeks each year—until, one day, they vanished without a trace. What began as a search for a lost species soon became something much more profound: a confrontation with ecological grief, a meditation on hope, and a powerful call to protect the natural world while we still can.

Why Do We Do That?
Ella Al-Shamahi explores evolutionary mysteries in More Play with Brenna Hassett. BBC Studios Audio Producer: Olivia Jani Additional Production: Emily Bird Series Producer: Geraldine Fitzgerald Executive Producer: Alexandra Feachem
Paleoanthropologist Ella Al-Shamahi asks why do humans play? The Neanderthals are a species that was so close to us that we could reproduce with them, they had creativity, technology and they made art - handprints on cave walls and painted shells strung into necklaces. But it turns out the Neanderthals had shorter childhoods than us. Their children grew up quicker than their Homo sapiens counterparts. We don’t know why Neanderthals went extinct. It is probably for a few reasons but is it possible that us having these longer childhoods, having more time to play, might have given us a creative edge. There are probably more important reasons for our survival over them but it is food for thought. And we are still playing, anthropologist Brenna Hasset says play is part of learning how to be an adult so depending on where you grow up influences the type of games children play.

Paleoanthropologist Ella Al-Shamahi looks at the evidence for what people want in a partner and how it changes as they get older. Psychologist Julia Stern from the University of Bremen shares the results of a study which recruited people from a singles night in a Berlin club and followed them for 13 years.

Dance seems like such a natural thing, a good beat comes on and you can’t help it, you might find yourself bobbing, even the rhythmically impaired might find themselves tapping their fingers along to the music and it starts early - one study has shown that babies as young as 5 months engage in rhythmic movements. Every culture on earth dances and yet look around at the rest of the animal kingdom… besides birds, can we say that other animals dance? Paleoanthropologist Ella Al-Shamahi asks why do we dance?…

Why Do We Do That?
Humans have evolved to drink alcohol, or at least to be able to metabolise it. And we share this ability with our closest living relatives, the chimpanzees and gorillas, who are also able to convert alcohol into sugar. It gave our ancestors an advantage because we could eat rotting fruit from the forest floor and convert the alcohol into sugars, providing a source of nutrients that not all species could digest. This is also known as the drunken monkey hypothesis. But paleoanthropologist Ella Al-Shamahi asks Professor Robin Dunbar if alcohol is why we go to the pub today.…

Nature is charismatic, a good view can take our breath away and a walk in the woods can help de-stress our frazzled minds. But have we always been this way? Because after all, our early ancestors didn’t have cities to escape from. Is an affinity with the natural world around us, something we inherited?

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, who investigates children from very different cultures to discover when and how they develop this very human ability and professional poker player Liv Boeree to discover the art of bluffing.

Why Do We Do That?
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 depending on our mood, e.g. if we’re feeling scared, nervous or happy. So, do we handshake to literally sniff out the other person? Ella speaks to neuroscientist Dr Eva Mishor from Weizmann Institute of Science to hear about her fascinating studies involving hidden cameras, life-size mannequins, sweaty smells and why handshakes can help us make better decisions. Great British Bake Off star Michael Chakraverty recounts a particularly important handshake during bread week.…

Why Do We Do That?
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 mechanism to deal with negative emotions? It doesn’t seem to bother comedian Eshaan Akbar, who believes procrastination is a good thing……
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 been shown to give away clues about your genetic information via smells - and why we find the smell of someone who is genetically compatible with us more attractive.…

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?

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 Presenter Clara Amfo comes on to talk about love, break-ups and heartbreak. Dr Freddy van der Veen, Associate Professor of Psychology at Erasmus University in Rotterdam reveals the very real signals that travel from our brain to our heart, which may have served an evolutionary purpose.…

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 ancestor laughed. So what is the purpose of laughing? Ella talks to Professor Sophie Scott from University College London and stand-up comic Ria Lina.…
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 dogs are a part of our story because of how useful they are. From the mundane everyday hunting and guarding to the epic stories of life saving dogs . But how did we get here? Oxford Professor Greger Lawson studies ancient dog DNA and thinks the evolution from wolves into dogs began when we both realised we could help each other.…

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 has been less easily explained until now. Why are they so helpful? Why do they stop having children of their own? Why do we have grandmothers?!
