5. Where Did Eukaryotic Cells Come From? - A Journey Into Endosymbiotic Theory
22 Jul 2019 · 10 min
1.8 billion years ago, a cell ate another cell, but it didn't digest it, and without that happening, we would not exist. This week we explore the origins of eukaryotic cells and ask the question, "Are our cells more than ourselves?"

29 Jul 2019 · 10 min

2 Sept 2019 · 10 min
Death is inevitable and mysterious, even in the microcosmos. Stentors, heliozoans, and yes, even tardigrades, experience death in many different ways.
12. Euglenoids: Single-Celled Shapeshifters
9 Sept 2019 · 10 min
Euglenoids have had a very, very long time to evolve, and that has led to the things they have evolved into being extremely diverse—so diverse that, combined with the varied shape-shifting abilities of its member species, euglenoids have proven challenging to both identify and classify.
