The first humans originated in Africa’s Great Rift Valley, a large lowland area caused by tectonic plate movement that includes parts of present-day Ethiopia, Kenya and Tanzania. Human ancestors traveled in all directions, constantly in search of abundant food resources and new places to inhabit.
Q. What did Stone Age people eat?
Their diets included meat from wild animals and birds, leaves, roots and fruit from plants, and fish/ shellfish. Diets would have varied according to what was available locally. Domestic animals and plants were first brought to the British Isles from the Continent in about 4000 BC at the start of the Neolithic period.
Q. Why is it called Stone Age?
Why is it called the Stone Age? It is called the Stone Age because it is characterised by when early humans, sometimes known as cavemen, started using stone, such as flint, for tools and weapons. These stone tools are the earliest known human tools.
Q. What is the oldest race?
An unprecedented DNA study has found evidence of a single human migration out of Africa and confirmed that Aboriginal Australians are the world’s oldest civilization.
Q. What planet rains rubies?
The team, led by Dr. David Armstrong, believes the clouds on HAT-P-7b contain corundum, the mineral that forms rubies and sapphires. Using the Kepler space telescope, the team noticed that the planet, which is twice the size of our Sun, shimmered like a gemstone.
Q. Is there gold on Mars?
Magnesium, Aluminium, Titanium, Iron, and Chromium are relatively common in them. In addition, lithium, cobalt, nickel, copper, zinc, niobium, molybdenum, lanthanum, europium, tungsten, and gold have been found in trace amounts.
Q. What is Diamond Rain?
This “diamond rain” would convert potential energy into heat and help drive the convection that generates Neptune’s magnetic field. There are some uncertainties in how well the experimental results apply to Uranus and Neptune. Water and hydrogen mixed with the methane may alter the chemical reactions.
Q. Does Mars have oil?
If Mars possessed an Earth-like biosphere in the past, Mars may contain subsurface deposits of oil and natural gas indicating past life. Subsurface oil and natural gas on Mars would probably cause seepage of hydrocarbon gases such as methane at favorable locations on the Martian surface.
Q. Does NASA use gold?
Gold is also used by NASA in the construction of spacesuits. Because of its excellent ability to reflect infrared light while letting in visible light, astronauts’ visors have a thin layer of gold on them to protect their eyes from unfiltered sunlight.
