what is the correct answer

Question 14 1 pts Which of the following is the MOST IMPORTANT line of evidence concerning the possible causes of the recent megafauna extinction? The megafauna extinctions were global in scale and preferentially targeted those animals most vulnerable to environmental changes. The megafauna extinctions occurred during the most extreme periods of climate change, as shown by changes in plant and fire patterns. The megafauna extinctions were most severe in the areas where humans had first evolved, and their severity decreased with distance. The megafauna extinctions were most severe in high latitude (polar or near-polar) areas with the greatest changes in climate conditions. The megafauna extinctions match the timing of when humans first reached new areas that had not been previously exposed to humans
