The recent discovery of Khentkaus III's tomb in Abusair, Egypt, fills in a "black patch" in the history of the Old Kingdom, according to dig leader Professor Miroslav Barta.

Egyptologists are optimistic that a second chamber may soon be found behind King Tutankhamun's tomb, based on results of scans from the Valley of the Kings. One archaeologist has speculated that if the second chamber exists, it could be Queen Nefertiti's long-lost burial place.

A female mummy discovered in 1898 in tomb KV35 in the Valley of the Kings, and dubbed 'The Younger Lady' has been speculated to be Nefertiti. DNA tests in 2008 showed she was not only King Tutankhamun's mother, but also his aunt (she was sister to his father Akhenaten). Many Egyptologists say this DNA evidence means it's unlikely the remains are those of Nefertiti.

According to a paper published last May by the science journal Nature, the oldest stone tools made by our human ancestors were discovered in northwestern Kenya and date back 3.3 million years -- about 700,000 years before the oldest tools previously unearthed.

Last year, an international diving team explored flooded caves in Madagascar, and uncovered the largest cache of fossils in the country to date, including the remains of gorilla-sized lemurs, pygmy hippopotamuses, horned crocodile and elephant birds.

The 15th-century Qaitbay Citadel in the port city of Alexandria occupies that same location where the famous lighthouse once stood -- partially destroyed in the 11th century by an earthquake, and totally decimated by another in the 1300s. Today the citadel functions as a maritime museum.

The Temple of Karnak, in the southern Egyptian city of Luxor, can be visited on luxury cruises down the Nile, along which tourists can track 5,000 years of history.
