Hilde Mangold and the Organizer of Life | Great Minds
Experiments conducted by Hilde Mangold and Hans Spemann taught us how an animal develops from a small ball of cells into an organism with distinct, functioning parts. The work was a foundational contribution to the field of developmental...

The Reproductive System
Paul Andersen starts with a brief description of asexual and sexual reproduction. He explains how meiosis ensures variation in the next generation. He describes the important structures in the male and female reproductive system. He...

Animal Development: We're Just Tubes - Crash Course Biology
Hank discusses the process by which organisms grow and develop, maintaining that, in the end, we're all just tubes.

Animals
Paul Andersen briefly surveys members of the Domain Animalia. He begins with brief description of the phylogeny of animals. He then describes the characteristics of all animals, heterotrophy, multicellularity, motility and blastula. He...

The Origin of Multicellular Life: Cell Specialization and Animal Development
Alright, so we've learned a lot about the origin of life. We learned about how the first organic molecules can have formed spontaneously, and how they might have assembled into the first protocell. From there, endosymbiotic theory tells...

What is Zygotic Cleavage?
In this video, we explore how the zygote undergoes a variation of mitosis called cleavage.

Stages of Animal Development: Cleavage, Gastrulation, Organogenesis
Before diving into animal diversity, we need a bit more information about animal development, as it will help us understand what we're looking at later. We know that animals reproduce sexually, so a sperm fertilizes an egg to yield a...

An Introduction to Embryonic and Fetal Development
Developmental Set: 1. This clip introduces the early stages of embryonic development and the process of cellular differentiation that gives rise to organ systems during fetal development.
Curated OER
Reproductive System
Begin looking at reproduction by contrasting sexual reproduction with asexual reproduction. Sexual reproduction gives us genetic variation as meiosis creates brand new chromosomes through cross over. Male and female anatomy is covered,...

Biology Lab - Mitosis and Meiosis
Paul Anderson gives an explanation of how to conduct a biology lab to see mitosis and meiosis. This clip is directed at teachers and shows how to use an onion root and the fungus sordaria to count up the phases and draw a cell cycle pie...
