Paul Andersen starts with a brief description of the history of life. He then discusses the seven characteristics of life and why viruses are not alive. He then describes the three domains in the current classification system and...

Evolution & Classification of Life | From Single Celled Bacteria to Humans

A video entitled “The Classification of Life” which describes taxonomy and how all organisms on Earth are organized according to the Linnaean system.

Paul Andersen explains the current classification system that we use in Biology. He starts with a brief history of taxonomy. He explains how the goal of classification is to reflect evolutionary relationships. He then explains how...

Hank tells us the background story and explains the importance of the science of classifying living things, also known as taxonomy.

The video describes the development of a new classification system for all plant and animal life called DNA barcoding. This system uses a specific area of mitochondrial DNA as a unique species identifier, providing a more scientifically...

Until recently, all classifications of life, including the expansion from two kingdoms to five kingdoms, were based on physical observations of how things looked, even under a microscope. This is how the closeness and relationships...

The classification of animal groups is essential to the the development of modern biology—but it's extremely complicated. Trying to shoehorn the messy, complicated web of interrelationships that is biology into neat boxes has resulted in...

Alan Kapuler is a man who thinks on big time scales, and across wide geographic spheres of reality. A molecular biologist by training, as a young adult, Kapuler experienced an almost spiritual connection from working with plants. Years...

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...

In this video, we explore the challenging task of classifying the millions of different living things on our planet. By understanding classification principles and utilizing these tools, taxonomists contribute to our understanding of the...
