	As you may be aware we are preparing an exhibition as part of 
a research project on how children learn and understand evolution. As 
part of this project we are looking for examples of exhibits that 
relate to natural selection as the central thesis of Charles Darwin 
which suggests that within every population of living organisms there 
are random variations which have different survival value. Those 
which aid survival (or enhance reproductive capacity) are 'selected' 
by being genetically transmitted to succeeding generations.  So the 
elements of natural selection are:

	random variation of individuals within populations
	inheritance of traits
	selection of traits
	time for this to occur
	adaptation to environment

Would you let me know if you've developed exhibits that engage 
visitors on these topics or seen one that you think was particularly 
effective?

On-line or off-line and I will summarize for the list.
