Let's dive deep into the fascinating world of Evolutionary Psychiatry, building on our previous exploration of Evolutionary Psychology (from 100 episodes ago!). In that episode we compared the brain to an information processing device shaped by eons of evolution? Today, we venture further from the shore, exploring how our mental software, which evolved for ancient challenges, copes in our modern world. We'll unravel the mysteries of mental disorders through the evolutionary lens, questioning why traits beneficial in our past might be problematic today.    Music in this Episode   Memory Wind by Podington Bear, License (CC BY 3.0): Artist website: soundofpicture.com   Submerging Green by Podington Bear, License (CC BY 3.0): Artist website: soundofpicture.com   Poor Wayfaring Stranger by Podington Bear, License (CC BY 3.0): Artist website: soundofpicture.com   Climbing the Mountain by Podington Bear, License (CC BY 3.0): Artist website: soundofpicture.com    

The Foundations of Evolutionary Psychiatry Part 1

The "Evolution Talk" podcast needs your help! I have some great ideas for the show and for continuing to bring you free content. The truth is that the expense of keeping the show active and producing new episodes has become prohibitive.   I’ve researched different funding options, including Kickstarter, sponsorships, and grants for science education.   I’ve settled on a Patreon. This will enable me to plan for the next season.   More information about how you can help support the show is at EvolutionTalk.com/Support . You can also go directly to Patreon.   In the meantime, there are still over 140 episodes available for your enjoyment!   I appreciate you for all of your support over the years.   Thank you! Rick

Evolution Talk Needs Your Help

Sagan once pondered, "How did the molecules of life arise?" This question, echoing through the annals of scientific history, brings us to today's episode. We've long understood the mechanics of evolution, but the origin of life itself remains a captivating mystery. From Darwin's elegant theory of natural selection to the curious idea of Spontaneous Generation, we'll dive deep into the evolution of thought on life's beginnings. We'll also unravel the groundbreaking Miller-Urey experiment, which mimicked Earth's early conditions to create organic molecules.    Music in this Episode  Orchestral Rise & Confusion by Tim Kulig, Free download: https://filmmusic.io/song/11275-orchestral-rise-confusion, Licensed under CC BY 4.0: https://filmmusic.io/standard-license Under The Surface by Tim Kulig, Free download: https://filmmusic.io/song/10639-under-the-surface, Licensed under CC BY 4.0: https://filmmusic.io/standard-license Gamma 135 175 Water Meditations by Tim Kulig, Free download: https://filmmusic.io/song/10713-gamma-135-175-water-meditations, Licensed under CC BY 4.0: https://filmmusic.io/standard-license Psychic Cube by Tim Kulig, Free download: https://filmmusic.io/song/11767-psychic-cube, Licensed under CC BY 4.0: https://filmmusic.io/standard-license Simple Space Score by Tim Kulig, Free download: https://filmmusic.io/song/8867-simple-space-score, Licensed under CC BY 4.0: https://filmmusic.io/standard-license Scorpion Standoff by Tim Kulig, Free download: https://filmmusic.io/song/8471-scorpion-standoff, Licensed under CC BY 4.0: https://filmmusic.io/standard-license Blue Scorpion by Kevin MacLeod, Free download: https://filmmusic.io/song/3451-blue-scorpion, Licensed under CC BY 4.0: https://filmmusic.io/standard-license

From A Warm Pond...

Our story starts with cells.  Not our cells but the cells of our closest relatives.  The great apes. Within the nucleus of their cells the great apes have 24 chromosome pairs.  We have 23 pairs.  If we share a common ancestor, what happened to the missing chromosomes? Evolution Talk is also a book!

The Case of the Missing Chromosomes

Vestigial features and atavistic traits are all evidence of our past.  They are glimpses into a species distant past. We have nature and evolution by natural selection to thank for it.

Suboptimal Design

When it comes to personal IDs, we have many.  There’s your driver’s license, passport, online username, among other human-made forms of proving who you are.  Then there are those that nature gave you that’s yours and yours alone.  Like your DNA. And then there are your fingerprints.  Other than leaving incriminating evidence behind if you’ve committed a crime and weren't careful enough to wipe them away or wear gloves, what are fingerprints good for?

About Those Fingerprints

Attics aren’t the only places you’ll find old secrets from the past, begging to be rediscovered or let out. You have them in you as well. I’m not talking about the the type of secrets you keep to yourself and only tell close friends. I’m talking about those like the ones you’ll find in old attics.  Secrets you don't even know are there.  These secrets are locked in your DNA. Every once in a while, those secrets come back to haunt us. Evolution Talk is also a book!

What's Old is New Again

Ants have mastered the art of cooperation.  They have highly organized social structures, caste systems, and with everything they do, they do for the colony.  They are in a sense, a superorganism with each ant contributing to benefit of colony, like cells in a functioning body.

Evolution by natural selection is not perfect, nor does it strive to be.  It doesn't strive to be anything at all.  An adaptation that is beneficial under one set of circumstances may be a detriment under another. There are also some wonderful by products - like reading and writing.  Did we evolve to read and write? Once again, imperfection reigns. Evolution Talk is also a book!

Reading, Writing, & Evolution

Summer Break

The Homo Naledi have been intriguing scientists since their discovery in 2013, challenging our understanding of early human life. In this episode, we explore the burning question: how did they end up in the incredibly difficult-to-reach Dinaledi chamber? From the possibility of using fire to lighting their way to the evidence of intentional burial, we are slowly uncovering the secrets Homo Naledi left behind. We delve into their potential cognitive abilities, including abstract thinking and symbolic thought, and what their burial rituals could mean about their understanding of mortality.

Journey with us from Britain’s south coast, where hoverflies fool predators with wasp-like outfits, to the deceptive bands of the scarlet kingsnake in southeastern US. Marvel at the daytime antics of clearwing moths, mistaken for bees, and question the taste of the Viceroy butterfly, a monarch look-alike. As the lines between disguise and reality blur, we explore the intriguing dance of adaptation and survival in the animal kingdom. It’s nature’s never-ending Halloween party.

From the quiet roads of New Hampshire, where snapping turtles are more common than lizards, to the depths of our evolutionary past, we'll grapple with the idea that we may still carry a piece of our reptilian ancestors within us. But don't be too quick to believe popular pop-psychology. We'll explore what the Triune Brain model tells us about our so-called "reptilian brain" and how it shapes our instinctual responses. We'll question if there's a lurking Allosaurus within our minds or if it's just an oversimplification of a complex organ. Evolution Talk is also a book!

Our Reptilian Brain?

Using the metaphor of a simple beat evolving into a complex symphony, we explore how small-scale genetic changes within populations give rise to new species. From microevolution to macroevolution. Here, the role of natural selection is handed over to the discerning ears of different audiences to select the music that survives and evolves. From a simple beat to a grand symphony, we trace the evolution of life. Evolution Talk is also a book!

It's All One Song

In this episode, the focus is on macroevolution, which deals with larger scale evolutionary changes compared to microevolution. Macroevolutionary changes can give rise to new species, and its results can be seen in the fossil record. By piecing together fossils, researchers can observe macroevolutionary patterns, predict transitional organisms, and even locate potential fossil sites. Whales provide a compelling look at macroevolution, as their evolution from land-dwelling mammals to aquatic giants is documented in the fossil record. The journey of whales, from the wolf-sized Pakicetus to the fully aquatic Basilosaurus, showcases the power of macroevolution. Evolution Talk is also a book!
