Cute, informational book about where we all came from. Still quite an advanced thought process that would be better for older kids, but for those interested in science and biology, it would be great. Probably a good addition to an elementary science classroom for early learning, too.

This science book for kids explains the concept of LUCA, the last universal common ancestor. It explains it in engaging and simple prose and the illustrations are wonderful. A great addition to any collection of books for the curious, inquisitive kid.

Although I think this picture book is going to be over the head of most young children, I don't see a problem with reading it to children. There are a ton of board books that talk about complex science topics. This is just laying a foundation.

The illustrations make the information provided easier for young readers to understand. I think this would be great for 5+.

Thanks to Netgalley and Owlkids books for this ARC!

A picture book introduction to our last universal common ancestor “Luca” the single celled organism from which all other life on earth evolved, this tries to pack a huge concept into a tiny book. Overall, I think it does a decent job with a topic that is very hard to grasp for the age range that doesn’t really have a good grasp of time or evolutionary concepts. The illustrations were good, the text was not too heavy, and my 6 year old stayed engaged with it.

Karen Krossing relates the story of our first universal ancestor with lyrical language that comforts and reassures. She explores a complex subject in a way that's understandable for the youngest reader yet doesn't talk down. This reads like a lullaby yet explores so much. It's a book that families will read together time and again.

This non-fiction text tells children about LUCA - Last Universal Common Ancestor and how life on earth all began. With beautiful pictures and fairly simple text, this very complicated idea becomes something that even young children can understand. It is a neat book and definitely worth giving a try if you or your child is super interested in biology and science. Thanks to Netgalley and the publisher for giving me the chance to read this book!

I honestly don't even know what I read. This book focuses on the last common ancestor we have and traces down to an itty bitty organism?? I don't think kids would understand or like this book at all.

One Tiny Bubble is the story of the cell that divided and began the evolutionary process of creating all forms of life on Earth. While the text is simple, the subject matter is still difficult for young children to understand.

I received an electronic ARC from Owlkids Books through NetGalley.
Krossing shares information about LUCA (Last Universal Common Ancestor) and takes readers on a journey from this first cell through forming everything on the planet. She explains what is known in language elementary level readers will understand and can follow. Lo brings LUCA to life in her artwork and captures what the world probably looked like at that time. Informative text and a glossary are included at the end of the book. Sources are also provided for further research.

One Tiny Bubble is a really approachable book to learn about LUCA (Last Universal Common Ancestor). This would be a great book for any child interested in science or the universe. It has a bright, simple illustrations.

One Tiny Bubble is an interesting story about LUCA (Last Universal Common Ancestor) and how LUCA came to life in an unfriendly world, the beginning of our family trees. The book explains what LUCA is and how LUCA was able to come to life and thus began the creation of so many living organisms.

The pictures are very cute for young children and the story is easy to follow. Thank you NetGalley and OwlKids Books for the advanced copy. All opinions are my own.
