As requested by listener GT, we are going to talk all about moles today! Join us for the evolutionary history of the Talpidae family, English prophecies about moles, how much a mole head is worth in 2026 money according to the 1533 Vermin Act, and a lot of Red List data.

Last week we introduced some discussion on bee/pollinator declines. This week, we will discuss a perspective by Jaboury Ghazoul- a professor at ETH Zurich- who argued in a 2005 paper that labelling a pollinator decline crisis was, in fact, premature. Sources for this episode: TBA

Once again adapting a blog post into an episode, we are going to be examining a paper from 2016 which gives a potential new perspective on bee/pollinator declines. It argues that the contribution of non-bee pollinators to pollination services might be greater than we think. Sources for this episode: TBA

There is a number we use in genetics to represent how inbred a particular individual- e.g.: Charles II of Spain, Ptolemy XIII or Danaerys Targaryen- is. On today's episode, thanks to guidance from a blog post I found very helpful on the subject, we are going to take you through how this number is calculated for some simpler cases.

The term phylogenetic tree often gets bandied about, but how exactly do you construct one? Using three exemplar snake species and the differences in amino acid sequences in a common protein, let's build one together and explore how the process works. Sources for this episode: TBA

We're going to be adapting an old Biopedia blog post today and examining how biofilms might be relevant in the generation of Alzheimer's. Sources for this episode: TBA

Happy seventh Darwin Day! Today on the podcast, we are going to examine the family tree of Charles Robert Darwin. Let's explore more than ten generations of Darwins, starting all the way back in the 16th century with William Darwin Sr. Sources for this episode: TBA

I have become a father! My firstborn daughter is here and is of course wonderful. However, the fact of her existence means that there may be some disruption to the podcast schedule. Thank you for your understanding!

As part of a triple feature with After Alexander and Autocrat, we will be discussing the olive tree today. Let's explore the biology and ecology of a tree species that is central to a myth covered on Autocrat, in a city which After Alexander explores the history of... Sources for this episode: TBA

Happy 2026! Or rather- 12,026. At least, according to one interpretation. It has been suggested that the Anno Domini/Common Era system of timekeeping has some limitations. So, Cesare Emiliani created a calendar in 1993 to combat these issues. Get ready to discuss a calendar which begins when human civilisations and farming did- at midnight, 1st January, 10,000 BCE. After that, we'll take you o...

It goes without saying that the Red Planet is very different to our own world. For one thing, the day and year length of Mars differ from those experienced on Earth. So how would hypothetical colonists deal with this? On our last episode of 2025, let's discuss the Suran calendar- originating from a paper from the 1990s and dealing with this exact question.

A silly question today- if you were to add together all of the X chromosomes of all of the people in the world, what would their total mass be? To answer this, we are going to have to estimate the mass of an X chromosome, examine how many cells are in a human body, and just how many people there are in the world...

Generation Beta is, according to futurist Mark McCrindle, just starting to appear in the world. So, today, let's examine the generations that have been given a label in societal consciousness since the Lost Generation all the way back in the late 1800s. Sources for this episode: TBA

Today, we are going to examine a paper studying the impact both age at first pregnancy and the interval between pregnancies has on the probability of various negative outcomes associated with childbirth. Sources for this episode: TBA

Charles Darwin makes his way south from Rio de Janeiro to Maldonaldo and the south of South America. Along the way, he witnesses some local activities and has time to show off technological marvels to the locals. NOTE: I have found out since recording that St Elmo's light or fire is a weather phenomenon in which plasma appears around anything with a structure like a rod in a vehicle, such as t...

In a sort of unofficial Part II to our discussion in episode 112, we are going to examine the data from the 1790 US census focussed on the towns of Danbury and Brookfield in Fairfield County, Connecticut. We will be using the data for each household to answer two questions- does the ratio between males and females deviate significantly from 50:50? And what is the average family size? Sources for t...

Something a bit different today- we are going to be following up from our discussion of namesaking and looking at suffix chains! Examples of links in such chains would include people like Theodore Roosevelt VII or John Smith III. Let's look at some real-life data- including data from the 1790 US census- to ask one question: how common or rare is each new link in the chain? Sources for this episode...

Today, we will be wiping out humanity to ask a simple question- what would happen if there really were only two people left to repopulate the planet? Let's meet our hypothetical protagonists Cornelius and Cornelia, and in the first part of this scenario we will examine how many children the pair could realistically have given certain assumptions.

A few weeks ago in episode 108, we talked about the largest species of snake to ever exist. Well, today we are travelling to the other end of the size spectrum to talk about the smallest snake in the world. This is Tetracheilostoma carlae , the Barbados threadsnake- which was thought to have gone extinct until the year 2025... Sources for this episode: TBA

Throughout history, there have been several claims of unusual longevity. For example, Pliny the Elder mentions several cases of people claiming to be 140 in a first century CE census. Moreover, there is a man in England who supposedly died at the age of 169 in 1670. However, they don't quite compare to the case of Colestein Veglin from July 1876. Sources for this episode: TBA

Previous episodes of the podcast have established the precedent of examining specific species or taxa. On today's episode, we are going to examine a snake. Not just any snake- the biggest snake to have ever lived... Sources for this episode: TBA

Pascal's Triangle is a useful concept in binomial theorem. However, it also has uses in biology. Today, we use it to answer the question- if you have X number of kids in a family or randomly chosen people in a sample, what is the probability of ending up with at least Y males and/or Z females?

Adam and Eve, Ask and Embla, Deucalion and Pyrrha... The cultures of the world seemingly love the idea of humanity descending from two founders. While this notion may not be in line with scientific thought, there are two individuals who everyone can trace either maternal or paternal ancestry to. Say hello to mitochondrial Eve and Y-chromosomal Adam... Sources for this episode: Berta, P., Hawkins,...

We know today that our planet Earth is billions of years old. However, the people of a few centuries ago would have been equally convinced it was only a few thousand years old. So what were some of these old ages, and how big a shift is it from there to the age we've arrived at today? Sources for this episode: TBA

It was one of the oldest individual organisms to have lived. And yet, in 2006, its story would come to an end. To find out how, come and join us on this adaptation of a post on the Biopedia website into audio format. Sources for this episode: TBA
