Biology is the study of life—a four-letter word that connects you to 4 billion years worth of family tree. The word “life” can be tricky to define, but a shared set of characteristics helps biologists identify living things. In this episode of Crash Course Biology, you’ll learn how all of life is connected, and why studying biology can help us better understand ourselves and our relationship to all living things.

"Are you breathing right now?"
Me, chugging caffeinated tea for dear life; "Thankfully, no." And that, too, is biology.
I watched Dr. Sammy on his Wired interview and thought "man, this makes me want to learn so much more about biology." So I searched for a biology crash course, and here he is! I'm so excited to learn more about this subject from someone so good at explaining this subject.
you're a legend
So excited to start the course 😂
Life is about surviving..surviving is either beautiful or painfull❤
I love your energy, Dr Sammy!
Biology is Bio
it is what it almost is nOT continuing
Ok really digging Doc Sammy's presentation
Grind
this is how i cram for my bio midterm
He's good, but i don't think anyone can beat Hank💚
This video makes a lot of fun
Genuinely thought/hoped this was voiced by Levar Burton at first, while not watching the video. Am disappointed it isn't, but Dr. Sammy does an excellent job and I love his energy!
if there is extraterrestrial life, its probably just single celled organisms or bacteria.
translation to arab please
This is a very informative video for educational purposes

Wow! I love this. Thank you Dr Sammy
my favourite subject in middle school waaaaay back when … 🌱
I love CrashCourse. It’s a lifesaver for me when I want to revise important concepts quickly. Even though I miss Hank’s narration, the new style is really charming too with the smart puns! Thank you to the entire team for bringing us such high quality content for free! Keep up the good work guys! 😊✨
Nice! A 2nd Crash Course Biology Series!! Great idea!!!
❤❤❤
❤❤❤
Thanks for this great video, Dr. Sammy!
Life is the most amazing thing that happened in the universe.
So would a virus be considered a parasite?
As soon as you can't explain, you prove your position. So called scientists & scholars are not yet clear on the defination of life!!!!!
It is so amazing that we know so little about our own selves & yet we are so proud.
maybe missing something but how does biology help fight dis/misinformation on social media?
OMG Dr. Sammy is so awesme ❤
