pls help me not bio just basic science
Transcribed Image Text:An evolutionary biologist is studying the relationship between fish species. She
studies undisturbed sedimentary rock layers at the bottom of the Atlantic Ocean. She

the fossils found in the top layer. Which statement best explains what the similarity
between the two layers suggests about evolution?
5
A
Fossils in the bottom layer were formed before those in the top layer.
B
Fossils are only found in sediments.
C
Life evolved slowly from earlier forms of life.
Fossils in the bottom layer are more complex than those in the top layer.
