Question

if all fossils observed across a long period of time are nearly identical, then that species was in a period of select during that tim select gradualism lineage transitional fossils stasis

Explanation:

The graph shows evolution has long periods of no change (flat lines) interrupted by sudden shifts. When fossils from a long time frame are nearly identical, this matches the concept of a species remaining unchanged, which is defined as stasis. Gradualism refers to slow, steady change, lineage is a species' evolutionary line, and transitional fossils are intermediate forms between species, none of which fit the described scenario.

Answer:

stasis
