Our hand in maladaptation

Maladaptation

In the previous post on The G-CAT, we talked about the role of maladaptation in the evolution of populations and species, and how this might impact their future. To summarise, maladaptation is the process (or trait responsible for) which causes a reduction in the fitness. As we discussed, this can come about a number of ways – such as from a shift in the selective environment or from fitness trade-offs in traits over time – and predominantly impacts on species by reducing their capacity to adapt. Particularly, this is important for small populations or those lacking in genetic diversity, which are already at risk of entering an extinction vortex and lack the capability to respond well to extreme selective changes (such as contemporary climate change).
