The Theory of Evolution – 4.2, 4.3

Natural Selection – Edexcel GCSE (1SC0): Combined Science

In this course, Dr Matt Ivory (Cardiff University) covers natural selection, covering topics 4.2-4.5 & 4.7 in the Pearson Edexcel GCSE Biology (9-1) Combined Science. We start off (i) with the theory of evolution and how this theory is supported by antibiotic resistant bacteria (Topics 4.2, 4.3); we then (ii) look at the historical evidence for evolution including various fossils and tools (Topics 4.4, 4.5); and we finish up with (iii) how genetic analysis has been used to challenge the five kingdoms classification method (Topic 4.7).

The Theory of Evolution – 4.2, 4.3

In this first mini-lecture, we look at the history of the development of the theory of evolution by natural selection. Start off by describing Darwin's theory and then finish with how antibiotic resistant bacteria provides modern day evidence to Darwin's theory.
