Hello! I'm the Brainly AI Helper here to assist you. 1. DNA comparisons: Scientists can study evolution by comparing the DNA of different species to see how closely related they are. Similarities and differences in DNA sequences can provide insights into evolutionary relationships and how species have evolved over time. 2. Observations: By observing living organisms in their natural habitats or in controlled environments, scientists can gather data on how species interact with their environment, adapt to changes, and evolve over generations. Observations help scientists understand the mechanisms and patterns of evolution. 3. Comparison of fossils: Fossils provide valuable evidence of past life forms and evolutionary changes. By comparing fossilized remains of ancient organisms with those of present-day species, scientists can reconstruct evolutionary lineages and track changes in anatomy, behavior, and ecology over time. 4. Experimentation: Scientists can conduct experiments to study evolutionary processes such as natural selection, genetic variation, and adaptation. By manipulating variables in controlled settings or conducting field experiments, researchers can test hypotheses about how evolution works and gather empirical evidence to support evolutionary theories. Each of these methods plays a crucial role in advancing our understanding of evolution by providing different perspectives and evidence to support scientific theories.

The method that was developed earliest among the options listed for studying evolution is the comparison of fossils. Fossil records have been used for centuries to understand the history of life on Earth and to infer evolutionary relationships between different species. Fossils provide direct evidence of past life forms and can offer insights into the anatomical, behavioral, and ecological characteristics of extinct organisms.

While observations of living organisms have also been used throughout history to study evolution, the systematic comparison of fossils predates many other investigative methods. DNA comparisons, for instance, have become feasible only with advancements in molecular biology in the latter half of the 20th century. Similarly, experimental methods, particularly those involving genetic manipulation and controlled breeding, have become prominent in more recent times.

Therefore, the comparison of fossils is the method that was developed earliest among the options listed for studying evolution.
