Question

what can scientists conclude based on their findings? (1 point) a the land masses were once connected, making it easy to understand why that kind of bird was in both locations. b these were two different types of giant birds, even if their fossils look nearly identical. the fact that they look so similar is a coincidence. c the fossils date to different time periods d a volcanic eruption caused the giant bird population to permanently relocate from nigeria to south america

Explanation:

This question relates to the theory of continental drift (a key concept in Earth Science, a subfield of Natural Science). When similar fossils are found in different land masses, the conclusion about connected land masses (supporting continental drift) is scientifically valid. Option A aligns with this: if land masses were once connected, species could exist in both locations. Option B's "coincidence" is unlikely (against biological evolution/geological theories). Option C has no basis (similar fossils often date to same periods if land was connected). Option D's volcanic eruption - based relocation is not a standard scientific conclusion for such fossil distributions.

Answer:

A. The land masses were once connected, making it easy to understand why that kind of bird was in both locations.
