Why Avocados Still Exist

The video explores the relationship between avocados and ancient American megafauna, explaining how large animals helped disperse avocado seeds. After these animals went extinct, humans played a crucial role in the avocado's survival and spread. The video also discusses the potential for future genetic modifications to make avocado seeds smaller, highlighting the positive impact humans can have on the environment.

What is the main reason for the large size of the avocado seed compared to other seeds?

• It evolved to be a toy for children.

• It evolved alongside large American megafauna.

• It was genetically modified by humans.

• It is a result of climate change.

Which of the following animals was NOT part of the American megafauna?

• Mastodon

• American lion

• Dire wolf

• African elephant

What was one of the debated reasons for the extinction of large mammals in the Americas?

• Rise in sea levels

• Increased volcanic activity

• Climate change

• Lack of food resources

How did humans contribute to the survival of the avocado after the extinction of large mammals?

• By genetically modifying the avocado tree

• By building greenhouses for avocados

• By creating artificial seeds

• By cultivating and spreading avocados

What is a potential future change in avocados that could help them survive in the age of humans?

• Avocados becoming more bitter

• Avocados changing color

• Avocado seeds becoming smaller

• Avocados growing on smaller trees
