Welcome to Episode 101! In today's show, we'll continue our exploration of the early metazoans by focusing on the large and diverse clade Cnidaria. Here we will see all manner of jellyfish, corals, and sea anemones, among many other bizarre and strange relatives, including tiny filter feeders and obligate parasites. This will be a deep dive to meet some of the weirdest animals alive today.
Welcome to Episode 100! Today's special episode will be a deep dive into the world of the Ediacaran biota. We'll explore the early days of the Ediacaran, and the changing world that would give rise to the earliest animal-like organisms. Then, we'll follow their evolution through the Avalon, the White Sea, and the Nama time periods to see how this Ediacaran life evolves, diversifies, and eventually responds to the presence of new forms in the early Cambrian. In this way, we will learn how the Ediacaran biota set the stage for all animal life that would follow after them.
Welcome to Episode 99! Todays show will explore the strange and cryptic creatures known as the Ctenophora, or the comb jellies. These incredible and basal animals are quite unlike anything else in the sea, such that they may hold the secrets to many long-standing mysteries of early animal evolution.
Welcome to Episode 98! Today we will be exploring the anatomy, life cycle, and ecology of the most basal animal lineage with children still alive today; the sponges. These unassuming filter feeders are revealed to be extremely fascinating and complex creatures, critical to marine ecology.
Welcome to Episode 97! Today we'll be exploring the evolution of the animal lineage, starting way back over a billion years ago with the ancesetral Opisthokonta. We'll look at how the earliest multicellular creatures formed the first animals, and the first lineages of animals that really took off and successfully colonized the worlds oceans, with descendents still swimming around to this day.
In this final episode on our phylogenetic exploration of the deutereostomes and the vertebrates, we'll take a look at the taxonomy and biodiversity of the mammals. The clade is the least species-rich of all the vertebrates, but their size and abundance make them key shapers of terrestrial, and many aquatic, ecosystems.
Very early in the evolutionary history of animals, there was a divergance that would ultimately lead to the creation of two major divisions in the Kingdom Animalia; the Protostomes & Deuterostomes. In this episode, we'll explore this ancient evolutionary split, the physiological differences between the two clades, and the modern descendant species that represents them today.
The animal endocrine system is a complex decentralized chemical communication network that coordinates growth and homeostasis across the whole organism. Hormones are a critical component of this system, and we'll explore the many forms they can take. And while we're on the topic of glands, we'll also cover the basics of the exocrine system.
