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?

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?

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.

Well, today we are travelling to the other end of the size spectrum to talk about the smallest snake in the world.

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.

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…

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…

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?
