Experts from the University of Cambridge in the United Kingdom said that the brains of early humans were larger than modern humans, and that modern humans were 10% shorter than early humans. This study subverts previous theories that modern humans have become higher and stronger with evolution. Scientists say that this evolutionary decay of humans has occurred in the past 10,000 years or so, probably due to the emergence of agriculture. After the advent of agricultural farming, humans were limited by the reduction of food types and the spread of diseases, so there was an evolutionary decay. phenomenon. Which of the following, if true, is the least likely to question a researcher's hypothesis? ['according to research, human large-scale agricultural farming was made 5,000 years ago.', 'Ten thousand years ago, people in Africa and modern human cars were good.', 'with the improvement of agriculture, the food types of humans are much more than 10,000 years ago.', 'There is no cure for early human illness, and the physically disabled have been eliminated in evolution.']
