However, our research shows that, when read a storybook about how a species trait evolved in response to an environmental change, children as young as five can learn about natural selection. They can also retain what they learn for at least 3 months (learn more about our storybooks and associated teaching materials here).

Having demonstrated that our book was effective for different groups of children, we wanted to investigate how broadly children could apply the knowledge they had gained if they heard two storybooks in a classroom setting. We found that, after discussing our books, 7- to 8-year-olds could accurately apply the logic of adaptation by natural selection whether they were reasoning about traits relevant to gathering food or camouflage. These results endured after a one month delay.
In 2017, we were also excited to publish our first storybook; "How the Piloses Evolved Skinny Noses.", so that teachers and parents everywhere would be able to access, and use, this tried and tested resource. Purchase here.
After demonstrating that children could learn adaptation by natural selection from our storybook, we explored what aspects of the book helped 5- to 8-year-old children learn. In this study, we show that the book discusses animal populations and their traits in specific ways that avoid common pitfalls that feed children's (and adults') misconceptions about species and evolutionary change.
Our initial storybook study was conducted in a quiet lab setting with children from middle and higher socioeconomic backgrounds. To see if our findings applied to a broader group of children, we tested a more diverse set of 5- to 8-year-olds in an after-school program. We replicated our initial results. Both 5- to 6-year-old children and 7- to 8-year-old children learned from our storybook.
We demonstrated that 5- to 8-year-old children can learn a basic but theoretically coherent explanation of adaptation by natural selection using our storybook. In this study, we also showed that children can retain what they learn for at least 3 months and apply it to a new context.
In 2018, we were delighted to publish a second book in our Evolving Minds series; this one entitled 'How the Dormacks Evolved Longer Backs'. Purchase here.
Research published in 2017 (Emmons, Lees, & Kelemen, 2017) demonstrates that, when this storybook is used alongside "How the Piloses Evolved Skinny Noses", children's learning is facilitated; understanding of natural selection is extended, as they understand its application to different animals.
