If pregnant crickets are exposed to a predatory wolf spider, their babies will hatch, exhibiting increased antipredator behavior and, as a consequence, improved survival from wolf spider attack. The mother cricket appears to be able to forewarn her babies about the threat when they are still inside her, so they would be pre-adapted to their external environment. This even happens in plants. If you grow two genetically identical plants – one in the sun, one in the shade – the sun-grown plant will produce seeds that grow better in the sun, and the shaded plant will produce seeds that grow better in the shade – even though they’re genetically identical. What’s happening is called epigenetics, external factors changing gene expression.
