Horrible Histories…

This entry is part 2 of 3 in the series Natural Selection

This is a sort of experiment to see if people who could not previously see my posts can now see my posts (do comment – you know who you are…)

It is also rather a fun song from the BBC.

Questions…

  1. Who came up with ‘natural selection’?
  2. Suggest a unique characteristic of mammals.
  3. Suggest one way in which reptiles and mammals differ.
  4. Name a mammal that lays eggs.
  5. What is meant by the phrase “transitional species”?
