Only 2 species of bacteria can undergo sporulation to form endospore.

In winter, many species undergo morphological changes that drastically reduce their body weight.

This species undergoes seasonal molts during the spring and autumn.

Many species also undergo a diet shift as they develop.

This occurs when a species undergoes significant biological evolution within a relatively short period.

Subsequently, the species undergoes very little change for long periods until the next punctuation.

Since its original discovery, the species has undergone a number of taxonomic changes.

Most species undergo submarine pollination and complete their entire life cycle underwater.

This species that make up this genus undergoes much change.
