In this special episode I discuss various topics in evolution and genetics with Art Woods of the Big Biology Podcast. We begin by analysing various ideas associated with the extended evolutionary synthesis, including plasticity, epigentics, and niche construction, discussing the extent to which these ideas are a challenge or merely an addition to the mainstream understanding of evolution. We then consider several common misconceptions about genetics, including the idea of DNA as a blueprint and genetic essentialism. We conclude with a discussion of some politically contentious aspects of genetics.

Special Episode: Evolution and Genetics

I discuss a variety of topics in both the natural and social sciences, exploring the many fascinating insights that the scientific method yields about the world around us.

Natural Sciences

Science & Medicine

Social Sciences

Science

An overview of climate models, beginning with a summary of the major types of models, and then a more detailed disussion of hte primitive equations and parameterised feedbacks that characterise the widely used Atmospheric General Circulation Models. We also discuss techniques for model validation and some evidence regarding the accuracy of various climate models. Recommended pre-listening is Episode 142: The Greenhouse Effect.

Episode 143: Climate Modelling

A detailed discussion of the greenhouse effect and its impact on Earth's climate. We begin with a discussion of Earth’s energy budget, the various greenhouse gases and their interactions with longwave radiation, and a summary of major sources of greenhouse gas emisions. We then examine the mechanisms of the greenhouse effect in more detail using the idealised greenhouse model and radiative transfer models. We conclude with an analysis of the sensitivity of Earth's climate to changes in greenhouse gas concentrations, and how this interacts with the atmospheric lapse rate. Recommended prelistening is Episode 141: Natural Climate Change.

Episode 142: The Greenhouse Effect

An overview of the natural mechanisms by which climate changes over time. Beginning with an introduction to the concepts of radiative forcing and climate sensitivity, we then discuss solar forcing, orbital changes, volcanic eruptions, and silicate weathering, covering how each process operates and the effects it has on Earth's climate over varying periods of time. Recommended pre-listening is Episode 140: A History of Earth's Climate.

Episode 141: Natural Climate Change

A journey through the history of Earth's changing climate, in which we explore how Earth's climate has fluctuated over the past billion years. After reviewing the various temperature proxies used to estimate past climactic conditions, we discuss the varying hothouse and icehouse periods of Earth's history, the onset of the Quarternay Ice Age, the current interglacial period, the anomoly of the Younger Dryas, the Medieval Warm Period and Little Ice Ages, and the rapid rise in temperatures during the twentieth century. Recommended pre-listening is Episode 90: Climate Systems.

Episode 140: A History of Earth's Climate

In this special collaboration with I Know Dino podcast, we discuss the history and impact of dinosaurs in popular culture and media. We cover the history of the scientific study of dinosaurs and how their presentation in media has changed over time with new discoveries, and what aspects of their behaviour and appearance tend to be presented accuracy or inaccurately. We also discuss lesser-known aspects of understanding dinosaurs, such as how changes in the atmosphere and ecosystem would affect dinosaurs of they were to be alive today.
