max2010maxim [7]2 years ago
4 0

Answer:“At Jebel Faya, the ages reveal a fascinating picture in which modern humans migrated out of Africa much earlier than previously thought, helped by global fluctuations in sea-level and climate change in the Arabian Peninsula.”

another thing: Hans-Peter Uerpmann, published and article about their findings in the magazine Science under the title, "The Southern Route 'Out of Africa': Evidence for an Early Expansion of Modern Humans into Arabia." They explained that they have found 125,000 year old hand axes of stone that look like early modern human tools ...

another thing:Researchers have uncovered stone tools in the Arabian peninsula that they say were made by modern humans about 125,000 years ago. The tools were unearthed at the site of Jebel Faya in the United Arab Emirates, a team reports in the journal Science.

Today fewer than 250,000 people make their primary living from food foraging. Where do the remaining food foragers often live?.
bekas [8.4K]

Less than 250,000 people currently depend on food foraging as their main source of income. The remaining foragers so frequently inhabit habitats (cold locations, woodlands, islands) where other methods of food production are not viable.

To forage is to look for wild food sources. It has an impact on an animal's fitness because it's crucial to its capacity for survival and reproduction. A subfield of behavioral ecology known as foraging theory examines how animals respond to their living environments by changing how they forage. There are two basic categories of foraging. The first is solitary foraging, which occurs when animals go hunting alone. The second is foraging in groups.

Today, fewer than 250,000 people rely on food foraging as their main source of income. Because other methods of food production are not sustainable in these environments (cold places, forests, islands), the remaining food foragers frequently live there.

If, on average, each person fishing in your local lake catches 3.5 fish per fishing trip, with a standard deviation of 1.2, what
dangina [55]

Answer:

Mean of sampling distribution=3.5

Standard error of sampling distribution=0.219

Explanation:

We know that

The average of catching fish per fishing trip=μ=3.5

and

The standard deviation of catching fish per fishing trip= σ=1.2.

We have to find the mean and standard error of sampling distribution of 30 fishing trips i.e. μxbar=? and σxbar=?

Mean of sampling distribution=μxbar=μ=3.5

Standard error of sampling distribution=σxbar=σ/√n

Standard error of sampling distribution=σxbar=1.2/√30

Standard error of sampling distribution=σxbar=1.2/5.4772

Standard error of sampling distribution=σxbar=0.219

Thus, the mean and standard error for a sampling distribution of 30 fishing trips are 3.5 and 0.219.

The north pole has no land, only ice, witch two countries have land closets to that pole ?​
aivan3 [116]

Answer:

The two countries with the closest land to the North Pole are Canada and Greenland (Kingdom of Denmark).

Explanation:

Geographers generally believe that the closest piece of land to the North Pole is Kaffeklubben Island, which is an island off the northern coast of Greenland. Kaffeklubben Island is located about 430 miles from the North Pole.  There are some semi-permanent banks of rock and gravel that might technically be claimed to lie closer to the geographical point. The nearest permanent settlement is Alert in the Qikiqtaaluk Region of Nunavut, Canada. The permanent population there however is only 62.  There are more people residing in Alert at any given time, but they are there temporarily because they man weather stations and other government and military posts in Alert.  It is 508 miles from the North Pole.  The North Pole is located in the center of the Arctic Ocean and it is covered with shifting pieces of ice.
