Adapting to a changing environment

2. The Peppered Moth
The Peppered Moth is found in many parts of England and Ireland. It is considered one of the best examples of animal adaptation to an changing environment.
It is found in urban gardens as well as the countryside.
This moth is considered a nocturnal animal as it has rarely been seen during daylight hours.

3. Camouflage
In the case of the Peppered moth, its colour is an important factor in whether it survives or became a food source for predators.
The colour of the moth allows it to blend in with the habitat it is living in.
The light coloured moth is effectively camouflaged when sitting on lichen covered or light coloured trees. The dark coloured moth blends in with darker coloured bark and surfaces.

4. Adaptation
The Peppered Moth’s ability to adapt to its changing habitat has allowed the species to continue.
During the Industrial Revolution in England the moth’s environment changed dramatically.
Due to the increase in pollution from soot and other pollutants, the lighter coloured Peppered Moth (or typica) population began to diminish as it was now easier for predators to see.
The dark coloured moth (or melanic) began to flourish as they could blend in with the darkened trees.

Habitats
The Peppered Moth’s survival was dependant on a specific type of habitat. Where there was a higher concentration of pollutants, the darker Peppered melanic moth flourished. This was due to the fact they were less visible to predators.
Since the Industrial Revolution, air pollution has fallen over time and this has enabled the green lichen species to recover in some areas. This lichen enriched habitat is important for allowing the lighter coloured Peppered typica moth to continue to be well camouflaged and safe from predators.
It is crucial for animal survival that their habitats are looked after. Animal species will not able to survive from adaptations alone, even though they have the ability to adapt to the ever-changing world, adaptations is a slow process.
