Answer:

The given blank can be filed with stasis.

Explanation:

There are various kinds of species that have been discovered in the world and had remained unmodified, that is, right from the start. This has been supported by their fossil records that in the geological strata they were witnessed unchanged. This phenomenon is termed as stasis, in which the species do not exhibit any kind of directional change. The starfish, lungfish, and the tribolates belong to this category, that is, their current time appearance is identical to the fossil records.
