Pompeii worms were discovered by French Marine biologists in the 1980's. How would biologists validated the evidence for the discovery of the Pompeii worm?
They have to check that is hasn't been discovered before by checking a similar specie to see if its different; and send the evidence to another party to be validated and checked independantly
3 of 6
Explain how Darwins Theory of evololution with variation can lead to a species evolving.
A species evoloving would be the survival of the fittest and the species having to compete for food and mates. The species with mutations which enable them to be better adapted would breed and compete and have a more successful survival.

What is meant by the term Speciation?
The formation of a new species through repeated natural selection
