Welcome to the Biologic Podcast, an audio exploration of the incredible world of living things.
The journey begins at the dawn of life, almost 4 billion years ago. In this ancient eon, biochemical reactions gave rise to ordered systems (the cell) capable of replication. The key to this replication is the genome, and the DNA itself.
At this point, the journey expands in scope; we will explore the process of evolution, then move through hundreds of millions of years of evolutionary history until we come to the modern day, to survey the modern world's biodiversity. Then we'll take a step back to look at the ecological interactions of all this life, and the resulting biomes that define the surface of our planet Earth.
Our journey through the biological realm takes a sudden turn; having learned about life at the grandest scale, we now return to the ground, to look in greater detail at the various organisms that share this world with us. We first explore the physiology & diversity of plants, and then same for the fungi. Moving from flora to fauna, we explore the physiology & diversity of animals, up to and including the human being.
The path is long and the lessons hard, but for the ever-curious listener, there are many great discoveries and insights to be had in the world of the biological.
The ability to move, freely & autonomously, is one of the defining characteristics of all but the most basal animals, distinguishing them from the stationary plants, and the creeping fungi.
Animals are some of the most complex and dynamic organisms on Earth, and their mechanisms for reproduction are just as varied and complex.
An animal uses its senses to perceive and engage with the world around it, which is critical when you can move around an environment, searching for prey, and escaping predators.
All animals must eat food to survive, but how an animal eats, how often, and what it eats, play a fundamental role in the animal's evolution.
Water is critical for life. So how does the animal body use its water? How does it maintain a healthy osmotic balance, to sustain life?
Compared to plants and fungi, the animals have the most complex bodies, with the most complex body systems. Today, we'll explore the process of development that creates this complex animal body.
