Final answer:
Further exploration revealed that Columbus had not landed in Asia, as evidenced by encounters with Indigenous peoples and the presence of non-Asian flora and fauna.
Step-by-step explanation:
How further exploration proved that Christopher Columbus had not landed in Asia?
Further exploration and evidence revealed that Christopher Columbus had not landed in Asia. One key piece of evidence is the fact that Columbus encountered Indigenous peoples who were not Asians but natives of the Americas. Additionally, subsequent explorers like John Cabot and Amerigo Vespucci verified that Columbus had not reached Asia but instead had discovered previously unknown lands.
Another important piece of evidence is the presence of flora and fauna that were not native to Asia but were found in the Americas. For example, Columbus and his crew encountered plants such as maize (corn) and animals such as turkeys, which were not known in Asia. These findings supported the conclusion that Columbus had indeed discovered a new continent.
