Yet in so doing, archaeologists are providing empirical support for climate change and revealing how ancient peoples coped with challenging environments.

Some empirical support for their assertions about 'economic rebalancing' effects would be nice.

Nobody objects to entrepreneurs generating real wealth, but the claim that multi-million payments are required to attract 'top talent' lacks any empirical support.

This allowed me to propose and then successfully test a hypothesis, one which has much empirical support even if its theoretical properties are a mystery.

Now it has empirical support.
