Around 2 billion years ago, life had plateaued in complexity, ruined the atmosphere, and was on the verge of self-annihilation. But then something strange and potentially extremely lucky happened that enabled endless new evolutionary...

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...

Everywhere you look on Earth, you’ll find wonderful and diverse living things, from tiny tardigrades to soaring sequoias. And incredibly, everything alive today, and everything that’s ever lived, is related. In this episode of Crash...

Around 10,000 years ago, somewhere in Africa, a microscopic parasite made a huge leap. With a little help from a mosquito, it left its animal host - probably a gorilla - and found its way to a new host: us.

The unexpected discovery of an entirely new domain of life was pretty huge and surprising - even if archaea do just look like bacteria. But, in recent years, it’s been their connection to us that's turned out to be particularly full of...

Oxygen is pretty great stuff, but this recently discovered organism couldn’t care less about oxygen. It breathes nitrogen and may offer a window into how the types of cells in OUR bodies may have evolved billions of years ago.

3 billion base pairs is a pretty typical genome size for organisms like us, but there are a few plants and animals with genomes so huge they completely blow this number out of the water. Hosted by: Olivia Gordon

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....

Oxygen is pretty great stuff, but this recently discovered organism couldn’t care less about oxygen. It breathes nitrogen and may offer a window into how the types of cells in OUR bodies may have evolved billions of years ago.

This Amoeba Sisters video starts with providing examples of prokaryotes and eukaryotes before comparing and contrasting prokaryotic cells with eukaryotic cells! Contents: 00:00 Intro 1:27 Modern Cell Theory 1:37 3 Domains (with examples...

Two separate groups of biologists reported fusing entire sets of Saccharomyces cerevisiae chromosomes together, and surprisingly, the actual number of chromosomes might not be as important as we thought.

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...

Hank lets us in on the meaning of life, at least from a biological perspective - it's reproduction, which answers the essential question of all organisms: how do I make more of myself? So, sex, how does it work?

3 billion base pairs is a pretty typical genome size for organisms like us, but there are a few plants and animals with genomes so huge they completely blow this number out of the water.

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.

Forget lab rats — meet the Chinese or striped-back hamster, an unassuming little rodent whose role in research over the years has led to breakthroughs in genetics, pharmaceutics and more!

With a solid understanding of biology on the small scale under our belts, it's time for the long view - for the next twelve weeks, we'll be learning how the living things that we've studied interact with and influence each other and...

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...

Hank tells us about the city of Eukaryopolis - the animal cell that is responsible for all the cool things that happen in our bodies.

Organisms whose cells contain complex membrane-bound structures, called organelles.

otic)
- The differences and similarities between the structures of plant, animal, and bacte
rial cells
