Natural Selection - GCSE Biology Revision - SCIENCE WITH HAZEL

In this GCSE Biology revision video, Hazel goes through how natural selection and evolution, and how the original theories from Darwin and Lamarck were received by the scientific community.

These videos are designed to help with your GCSE science revision.

Hazel completed her undergraduate degree at St John's College, the University of Cambridge. She then did a PGCE (Post-Graduate Certificate of Education) before qualifying as a science teacher. She now works full time as a professional tutor.

These videos are revision tutorials specifically aimed at Edexcel IGCSE but can be used across all exam boards. Material required for A* is included.

I just wanted to thank you so much for all your exam revision videos. You made it so easy to understand, and your methods were so engaging…. I owe a lot of my A* Biology IGCSE grade to you, and I just wanted to thank you :) You’ve also helped to inspire a love of biology in me that will continue even though I’ve taken a different study path. Thank you!!!
