What are animal-like fossils doing in rocks a billion years old, and what does that mean for our understanding of their evolution and geologic time itself? Turns out, there might've been a long, slow-burning fuse that ultimately ignited...

From a single-celled common ancestor, evolution has brought us all of Life’s Greatest Hits — including butterflies, beetles, bacteria, and human beings. In this episode of Crash Course Biology, we’ll learn how evolution explains life’s...

We tend to think that evolution only goes in one direction— toward getting bigger and more advanced. But that’s not always the case. This tiny, simple animal, the Myxozoans, (yes, animal!) evolved from something bigger and more complex.

Explores classification in biology as well as taxonomy hierarchy: domain, kingdom, phylum, class, order, family, genus, and species with The Amoeba Sisters! This video also discusses the importance of scientific names and why...

Join the Amoeba Sisters in discovering how to use a dichotomous key to identify organisms. This video also touches on the importance of scientific names. Table of Contents: Intro 00:00 What is a Dichotomous Key? 0:29 Scientific Names vs....

Fairies do exist! Well, sort of...meet the fairyfly, the smallest insect on Earth that specializes in the magic of miniaturization!

Researchers might have discovered the 2 oldest plant-like fossils this week! Meanwhile, scientists learned more about another superpower of our favorite organism: tardigrades.

Compares and contrasts prokaryote cells and eukaryote cells before exploring organelle structures and functions! Video includes the modern cell theory and plant vs. animal cell comparisons. See table of contents by expanding video...

Oxygen is so essential for animals that every multicellular species we’ve ever studied has the ability to use oxygen to create energy... except one.

Hank introduces us to the "simplest" of the animals, complexity-wise: beginning with sponges (whose very inclusion in the list as "animals" has been called into question because they are so simple) and finishing with the most complex...

This video explains the process of cells dividing for reproduction, growth in numbers, and healing.

Biological organization is the hierarchy of complex biological structures and systems that define life. Cells are the basic units of all life, functional groups of cells form tissues, functional groups of tissues form organ, functional...

Learn what fungi and protist are and how they can cause 'Rose Black Spot' and 'Malaria'. We also cover vectors and parasites, and the symptoms and treatments of each disease

It gives introduction to Life Process.

Did you know that some organisms exist of just one cell? These simple organisms, like amoeba, are unicellular. They depend on simple diffusion for life They are usually too small to be visible to the naked eye, like bacteria, and so we...

When we discuss zoology, we are always also talking about evolutionary biology. And with evolution, we are sometimes concerned with origins. What is the origin of animals? What is the origin of eukaryotes? What is the origin of life on...

This live-action video program is about the word protists. The program is designed to reinforce and support a student's comprehension and retention of the word protists through use of video footage, photographs, diagrams and colorful,...

In this video, the teacher discusses the different kingdoms of living things. They explain that the animal Kingdom is the largest and most general category, including diverse organisms such as worms, marmots, and starfish. The video also...

In this online video lecture and tutorial on Cell Biology we will learn about cells, its shape, size and many other components of cell.

The classification system organises species into domain, kingdom, phylum, class, order, family, genus and finally species. ‘Kingdom’ is the second highest rank below the rank of domain in this sequence of classification. It helps us to...

Biological Classification Set: This clip introduces the four kingdoms of, Eukarya: Protista, Plantae, Animalia and Fungi.

Biological Classification Set: Introduces the concept of Domains in Biological Classification. Examines the difference between the bacteria, eukarya, and archaea.
