The advent of agriculture resulted in lifestyle changes from nomadic lifestyles to ones lived in homes, with domesticated animals, and land farmed using more varied and sophisticated tools. Art, architecture, music and religion evolved over the course of the prehistoric periods.

They spent most of their time searching for food. They hunted animals, caught fish, ate insects, and gathered nuts, berries, fruits, grains and plants.

Paleolithic people were the first to create clothing, usually out of leather or linen, and even created needles with eyes for sewing. Most Paleolithic inventions and technologies were in the form of tools and weapons, like bows and arrows.

During the end of the Paleolithic, specifically the Middle and or Upper Paleolithic, humans began to produce the earliest works of art and engage in religious and spiritual behavior, such as burial and ritual. Paleolithic humans were nomads, who often moved their settlements as food became scarce.

The Paleolithic Period was marked by the very primitive use of stone tools by humans therefore people were unable to control food production as effectively as they were in the Neolithic and following periods. That is why the most important factor affecting Paleolithic humans’ lives was B. climate.

In the Paleolithic period (roughly 2.5 million years ago to 10,000 B.C.), early humans lived in caves or simple huts or tepees and were hunters and gatherers. They used basic stone and bone tools, as well as crude stone axes, for hunting birds and wild animals.

Some Paleolithic people probably believed in animism, that everything has a spirit, including plants and inanimate objects. Paleolithic people also used artwork for religious purposes as well.

The Celts had their own languages which must have sound similar to the present used Gälisch. They did not have an own way of writing but used whatever came in handy: the Latin, Greek or Etruscan alphabet. In the Roman Times Latin spread over these areas, the language of the Old Romans.

We believe in the free flow of information Humans have a “natural” lifespan of around 38 years, according to a new method we have developed for estimating the lifespans of different species by analysing their DNA.

Studies in the biodemography of human longevity indicate a late-life mortality deceleration law: that death rates level off at advanced ages to a late-life mortality plateau. That is, there is no fixed upper limit to human longevity, or fixed maximal human lifespan.

Today, some scientists are keeping the dream alive. These thinkers believe genetic engineering, or the discovery of anti-ageing drugs, could extend human life far beyond its natural course. Cambridge researcher Aubrey de Grey thinks there is no reason humans cannot live for at least 1,000 years.

Some modern species may possess biological immortality. Certain scientists, futurists, and philosophers have theorized about the immortality of the human body, with some suggesting that human immortality may be achievable in the first few decades of the 21st century.

These days, while statistical life expectancy in the U.S. is about 80 years, living well into one’s 80s or 90s is a perfectly realistic expectation for many. Even centenarians — people who are 100 years old or more — are on the rise. In 2015, some 72,000 Americans were centenarians.

NASA Chief Says Returning Astronauts to the Moon Could Cost $30 Billion. It was always going to be expensive, but NASA’s first cost estimate for the agency’s push to land humans on the moon by 2024 is finally here — and it’s surprisingly cheap.

The extinction risk of climate change is the risk of species becoming extinct due to the effects of climate change. This may be contributing to Earth’s sixth major extinction, also called the Anthropocene or Holocene extinction.

In November 2015, Administrator Bolden of NASA reaffirmed the goal of sending humans to Mars. He laid out 2030 as the date of a crewed surface landing on Mars, and noted that planned 2020 Mars rover would support the human mission.

Lots of kids dream of becoming an astronaut, but Alyssa Carson is actually doing it. Alyssa Carson has loved space since she was a little kid. Now, aged just 20, she’s set her sights on becoming the first ever person to land on Mars.

A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. All seven crew members died, including Christa McAuliffe, a teacher from New Hampshire selected on a special NASA programme to bring civilians into space. …

Images taken by a Nasa spacecraft show that the American flags planted in the Moon’s soil by Apollo astronauts are mostly still standing. Now, researchers have studied photos of the same areas taken at different points during the day and have observed shadows circling the points where the flags are thought to be.

Does space have a smell? Still, astronauts have long been pretty unanimous in their consensus of what they can detect wafting through the void: It smells like “gunpowder, seared steak, raspberries, and rum,” according to a group of NASA astronauts who created a space-themed fragrance last year.

But in 1970 future Apollo missions were cancelled. Apollo 17 became the last manned mission to the Moon, for an indefinite amount of time. The main reason for this was money. The cost of getting to the Moon was, ironically, astronomical.

All soft landings took place on the near side of the Moon until 3 January 2019, when the Chinese Chang’e 4 spacecraft made the first landing on the far side of the Moon….Early U.S. uncrewed lunar missions (1958–1965)
