Episode 3 delves into how life began on a roiling, violent Earth and explores the story behind Victor Goldschmidt, the man who found the first clues to life's beginnings on our planet. Neil deGrasse Tyson takes viewers on a journey through space and time to witness the tenacity and creativity of life on Earth and the prospects of life throughout the universe.

Genetic breakthroughs have shed light on how life evolves in real-time. From filling in the missing links to creating a new species, in the last 50 years scientists have solved some of the biggest mysteries of evolution. In this episode, we look at revolutionary discoveries that shook the world and may shape our future.

The cosmos, with its billions of galaxies and countless stars, isn't the only one. We share our lives with another universe: The world of the small, of the viruses, of the bacteria. We call this strange hidden kingdom the Microcosmos. We share our world with the microcosmos. Will we coexist in an uneasy peace, or will it destroy us?
In 2020, A tiny virus caused a global pandemic, COVID-19. This pandemic makes people see the world completely differently, because there was an invisible universe, pretty much ignored for the most part. Very, very tiny things have a huge impact on our lives. The microcosmos is complex, while some parts kill us, others keep us alive. The microcosmos is responsible for the very oxygen that we breathe and the soil on which we live. And it will influence our future as we venture out into space.

What If we could talk to animals? For as long as we've shared our lives with pets, we've been seeking better ways to communicate with them. In Washington state, Alexis Devine and her sheepadoodle Bunny think they've found a way of making communication a reality. Alexis went further than most, with a set of communication buttons, each programmed with a pre-recorded word to help humans and animals speak the same language. She has 90 buttons with which to express herself and even seems to combine them into simple sentences. Bunny is paving the way in pet communication.
The undisputed masters of verbal communication are our pet parrots. They have mastered the art of vocal expression. Some parrots have even learned to fool devices designed to recognize human voices.

Our super friends in the animal world possess so many hidden superpowers. In the third episode we meet heat-seeking dogs, GPS-outfitted cats, and a sporty goldfish with squad goals.
When we think we know them inside out, dogs surprise us with something new. what sensory superpower have dogs been hiding all this time? They have a thermal sensor in the tip of his nose. In the wild, a dog could use his thermal nose to spot the heat of a prey animal, allowing him to hunt even if his other senses were impaired. It also explains that uncanny knack for stealing a warm seat.

All of our pets survived for thousands of years in the wild without any help from us, and this has led them to develop astonishing athletic abilities which we sometimes take for granted. As greyster dogs and endurance champ tortoises.
Dog scootering uses one or more dogs to pull a human riding an unmotorized scooter. Greysters are a naturally-athletic breed that can run at 20 miles per hour for five miles while handling these carriages. No other animal can run at this speed, exerting this power, and expending this energy for so long. So, what's their secret? Greysters' stride length can be a staggering 16 feet and they are super efficient at absorbing and using oxygen. Greyster dogs have nearly twice mitochondria inside their cells than humans.
