Step-by-step explanation:
The surprising hominin species found on an island living as recently as 13,000 B.P. was Homo floresiensis, also known as 'the Hobbit' or 'Flores Man.' This species was discovered on the island of Flores in Indonesia in 2003 and has been dated to approximately 100,000-60,000 years ago. Homo floresiensis was unique due to its small size, with adult individuals standing about 3 feet 7 inches tall.
