Question

The diagram below represents one possible evolutionary change that could have led lobe-finned fish to develop into the first amphibians. Amphibians are animals that live on land some of their life. This change from fins on the lobe-finned fish to legs and feet on the early amphibian is most likely due to (1 point) Responses variations among offspring, followed by natural selection variations among offspring, followed by natural selection increased competition between animals that had adapted to living on the land increased competition between animals that had adapted to living on the land the need to move to land because of increased competition for food in the ocean the need to move to land because of increased competition for food in the ocean a sudden mutation that changed the gills of the lobe-finned fish to lungs a sudden mutation that changed the gills of the lobe-finned fish to lungs

Answer 1

The best response to explain the evolutionary change from lobe-finned fish to early amphibians is **"variations among offspring, followed by natural selection."**

This is because evolutionary changes occur through gradual adaptations over time, where variations in traits among individuals lead to some being more suited to their environment. Natural selection then favors these advantageous traits, which can include the development of limbs for movement on land. The other options imply a more immediate or specific cause, which does not accurately reflect the typical process of evolution.
