TikTok secretly collected users’ MAC addresses: report

The video discusses a study published in Nature about ancient Polynesians possibly crossing the Pacific to interact with Native Americans in present-day Colombia. This contact led to DNA mingling and the exchange of crops, explaining the shared word for sweet potato. The study suggests Polynesians, known for their seafaring skills, likely reached Colombia, as Native Americans typically sailed closer to shore. A genomic study involving 800 indigenous people from various regions revealed shared genetic signatures dating back hundreds of years.

What role did the sweet potato play in the exchange between the Americas and Polynesia?

Why is it considered more likely for Polynesians to have arrived in Colombia than for ancient Colombians to have made the trans-Pacific voyage?
