Grouping Species Using DNA
Your child can explain why scientists now say birds are a type of dinosaur, not just their relatives. DNA helps sort living things into family groups.
In curriculum terms
Explain cladistics: organisms are grouped by shared derived characters, not just similarity; how phylogenetic trees are built using molecular data (DNA sequence alignment) and the molecular clock; explain why birds are technically a group within dinosaurs (crown Avemetatarsalia); distinguish convergent evolution (unrelated species evolving similar traits) from parallel evolution; introduce horizontal gene transfer and why the tree of life is more accurately a web; explain why classification systems keep changing as new data emerge

Try this together
Can your child explain why biologists now say that birds ARE a type of dinosaur — not just their descendants but literally within the dinosaur family tree? What does that tell us about how scientists classify animals?

Curriculum alignment
Where this fits in the official school curriculum — our best automated guess, not yet checked by a person.
This skill sits beyond Year 6 in the Australian Curriculum, so no F–6 code is matched. It also sits beyond the NSW K–6 syllabuses. It also sits beyond Level 6 in the Victorian Curriculum.
