Genetics & Evolution: Evidence for Evolution 🦧 GCSE Biology Learning & Revision
Update: 2025-06-24
Description
In this episode, we look at evidence supporting the theory of evolution.
Fossil records demonstrate the incremental changes in organisms throughout extended timeframes.
Furthermore, the development of antibiotic-resistant bacteria is highlighted as an example of natural selection.
The rapid reproduction of bacteria, coupled with mutations, leads to resistant strains when exposed to antibiotics. Surviving bacteria pass on their resistance, creating new lineages.
