Fish with a placenta struggle to adapt to rapid changes in the food supply. They probably evolved in a stable, food-rich environment. As ecosystems change under the influence of humans, they are experiencing greater difficulty in surviving than fish which lay eggs. Dutch researcher Bart Pollux has published his findings about this in the journal Functional Ecology.
