What are Structural Adaptations?Edit

Structural adaptations are physical features on an animal that have evolved over time to help them survive and breed.  Adaptations usually occur because of gene mutations or changes by accident.  For example, if one day a bird is born with a longer beak which helps him/her eat more food and is therefore healthier, that bird lives longer and breeds more passing along it's genes for a longer beak.  Over time animals who are better adapted to their enivronment survive and breed more often, furthering the spread of their genes and adaptations to further generations.  The chacteristics that do not help the species or hinder their survival slowly disappear because those individuals do not breed as much, or do not live long enough to breed.
