This compelling text examines evolution, its definition, and the scientific evidence that evolution has taken place. Readers explore the concepts of natural selection, Darwin's Origin of Species, genetics and evolution, population genetics, patterns in evolution and species concepts, the story of life and geological time, and human evolution. Easy-to-follow narratives offer students additional biological information in sidebars, such as "Closeup" boxes that give details about main concepts and "Try This" boxes that provide safe experiments for readers to perform. The text serves as a must-have resource on modern thinking about evolution and the history of evolutionary theories.

"A . . . rhythmic nonfiction picture book that introduces readers to the concept of DNA, and celebrates the similarities we share with all life forms--and each other!"--Provided by publisher.

Looks at the world of genetics, focusing on six-toed cats, stickleback hips, zombie genes, and other topics.

In rhyming text, illustrates through the concept of DNA how we are all part of the human race.

"This . . . chapter book biography chronicles the . . . life of Rosalind Franklin, a scientist who played a key role in the discovery of the double-helix structure of DNA"--Provided by publisher.

Microbes are everywhere! They live on and under the ground. They live in all kinds of water on Earth, even around the hottest deep-sea vents. They even live on and inside your body! Since the advent of powerful microscopes, scientists have been studying our world's smallest denizens. Many people get scared just hearing the words "bacteria," "fungus," and "virus" because of the diseases they cause. However, scientists have discovered many beneficial microbes that actually help support all life on Earth. Geneticists have sequenced the genomes of numerous microbes, extending our knowledge of the organisms and how they affect our lives.

"Inside every cell in the human body are tiny molecules that define all of a person's biological traits. [The author] explores DNA with curiosity and awe, pairing thrilling facts with clear explanations. Our human DNA might be 99% the same, but that last 1% difference makes each person unique"--Provided by publisher.

"A picture book biography about scientist Rosalind Franklin and her contributions to molecular biology, discovery of the DNA double helix, and study of viruses"--Provided by the publisher.

20,000 years ago, people crossed a great land bridge from Siberia into Western Alaska and then dispersed southward into what is now called the Americas. Until we venture out to other worlds, this remains the last time our species has populated an entirely new place, and this event has been a subject of deep fascination and controversy. No written records--and scant archaeological evidence--exist to tell us what happened or how it took place. Many different models have been proposed to explain how the Americas were peopled and what happened in the thousands of years that followed. A study of both past and present, ORIGIN explores how genetics is currently being used to construct narratives that profoundly impact Indigenous peoples of the Americas. It serves as a primer for anyone interested in how genetics has become entangled with identity in the way that society addresses the question "Who is indigenous?".

"Single mom Jessica Davis is a data and statistics wizard, but no amount of number crunching can convince her to step back into the dating world. Jess has been left behind too often to feel comfortable letting anyone in; she holds her loved ones close, but working constantly to stay afloat is hard... and lonely. GeneticAlly, a buzzy new DNA-based matchmaking company, claims to find soulmates through DNA. Her test shows an unheard-of 98 percent compatibility with another subject in the database: one of GeneticAlly's founders, Dr. River Pe?a. She already knows Dr. Pe?a, and this stuck-up, stubborn man is without a doubt not her soulmate. As the pair are dragged from one event to the next, Jess begins to realize that there might be more to the scientist than she thought"--OCLC.
