Doctor Who : Icons : Charles Darwin and the Silurian Survival
L. D. Lapinski

When Charles Darwin lands on the Galápagos Islands after a long voyage, he finds two things that really shouldn't be there. The first is a sunbathing Time Lord. The second is a Silurian skull...
As more Silurians - alive this time - are discovered by Darwin's crew, there is pandemonium. And when the island's volcano starts up, years ahead of schedule, it looks like all-out war.
The Doctor has his hands full. Can he keep Darwin - and his evolutionary theory- alive?
This time, the history of science is at stake.
