Ер нь бол хүн төрөлхтөн дэлхий гариг дээр анх үүсээгүй бөгөөд өөр гаригаас нүүдэллэж ирсэн гэх таамгийг батлах маш олон баримт байдаг юм байна.


Зөвхөн анагаах ухаан, хүн судлалын шинжлэх ухааны зүгээс гэхэд дараах баримтууд байдаг аж.

1. Хөлийн венийн судас бүдүүрэх өвчнөөр зөвхөн хүн өвддөг байна. Нийт хүм амын 80 хүртэлх хувь нь ямар нэг хэмжээгээр энэ талын шинж тэмдэг, зовиуртай байдаг.
2. 40-өөс дээш насныхны 85 хувь нь нуруу мурийх, бөгтийх, нурууны нугалам суух, зөөлөвч мөгөөрс гэмтэх, өвдөг ба шагайн үений үрэвсэл гэх мэт тулгуур эрхтний өвчнүүдээр өвддөг.
3. Сансарт удаан хугацаагаар ажилласан хүмүүсийг судлаад нэг сонирхолтой зүйлийг ажиглажээ. Хүн дэлхий орчмын тойрог замд гараад жингүйдлийн нөхцөлд дасах хугацаа нь ердөө 48 цаг байдаг байна. Харин тэдний эргээд дэлхийд буусны дараах газрын татах хүчний үйлчлэлд дасах хугацаа нь 21 хоногоос 6 сар хүртэл үргэлжилдэг байна.
4. Хүний арьсанд нарны шууд гэрэл удаан хугацаагаар үйлчилбэл түлэгдэн цэврүүтэж, арьсны өнгөн давхаргууд хууларч эхэлдэг.
5. Хэсэг хүмүүсийг гадаад орчноос удаа хугацаагаар тусгаарлан туршилт хийхэд хүний дотоод биологийн цаг нь 24 биш харин бараг 25 цагийн хэмнэлтэй болох нь тогтоогджээ.

Эдгээрээс үндэслээд хүн дэлхий гаригийн хүндийн хүч буюу газрын татах хүч, дэлхий орчимд тусах нарны гэрлийн цацраг, дэлхийн хоногийн хэмнэлд одоо хүртэл бүрэн гүйцэд дасан зохицож чадаагүй байна гэж дүгнэжээ. Өөрөөр хэлбэл хүн анх үүсэхдээ дэлхийгээс жижиг, татах хүч багатай, нарнаас арай хол оршдог, дэлхийгээс удаан хурдан эргэдэг гариг дээр үүссэн, эсвэл хүнийг тийм гариг дээр амьдрахаар бүтээсэн болж таарах нь :frog:

Earth life 'may have come from Mars'

By Simon Redfern
Reporter, BBC News, Florence

Life would face challenges on Mars today, but billions of years ago conditions might have been better
Continue reading the main story

'Fossil' protein clue to early life
Early Mars atmosphere 'oxygen-rich'
Tiny flaws 'sparked complex life'
Life may have started on Mars before arriving on Earth, a major scientific conference has heard.

New research supports an idea that the Red Planet was a better place to kick-start biology billions of years ago than the early Earth was.

The evidence is based on how the first molecules necessary for life were assembled.

The evidence seems to be building that we are actually all Martians; that life started on Mars and came to Earth on a rock”

Prof Steven Benner
Westheimer Institute for Science and Technology
Details of the theory were outlined by Prof Steven Benner at the Goldschmidt Meeting in Florence, Italy.

Scientists have long wondered how atoms first came together to make up the three crucial molecular components of living organisms: RNA, DNA and proteins.

The molecules that combined to form genetic material are far more complex than the primordial "pre-biotic" soup of organic (carbon-based) chemicals thought to have existed on the Earth more than three billion years ago, and RNA (ribonucleic acid) is thought to have been the first of them to appear.

Simply adding energy such as heat or light to the more basic organic molecules in the "soup" does not generate RNA. Instead, it generates tar.

RNA needs to be coaxed into shape by "templating" atoms at the crystalline surfaces of minerals.

The minerals most effective at templating RNA would have dissolved in the oceans of the early Earth, but would have been more abundant on Mars, according to Prof Benner.

Red or dead
This could suggest that life started on the Red Planet before being transported to Earth on meteorites, argues Prof Benner, of the Westheimer Institute of Science and Technology in Gainesville, US.

Why is Mars so lifeless?

No magnetic shield: Mars' magnetic field disappeared four billion years ago, allowing the solar wind to strip away the planet's atmosphere
The missing atmosphere: Mars has just 1% of Earth's atmospheric pressure, so heat from the Sun escapes into space, making the planet very cold
Too cold for liquid water: Mars sits outside the so-called Goldilocks Zone where the temperature is 'just right' for water to remain liquid - vital for life as we know it
BBC Science: What makes Mars so hostile to life?
The idea that life originated on Mars and was then transported to our planet has been mooted before. But Prof Benner's ideas add another twist to the theory of a Martian origin for the terrestrial biosphere.

Here in Florence, Prof Benner presented results that suggest minerals containing the elements boron and molybdenum are key in assembling atoms into life-forming molecules.

The researcher points out that boron minerals help carbohydrate rings to form from pre-biotic chemicals, and then molybdenum takes that intermediate molecule and rearranges it to form ribose, and hence RNA.

This raises problems for how life began on Earth, since the early Earth is thought to have been unsuitable for the formation of the necessary boron and molybdenum minerals.

It is thought that the boron minerals needed to form RNA from pre-biotic soups were not available on early Earth in sufficient quantity, and the molybdenum minerals were not available in the correct chemical form.


Meteorites from Mars have been arriving on Earth throughout our planet's history
Prof Benner explained: "It’s only when molybdenum becomes highly oxidised that it is able to influence how early life formed.

"This form of molybdenum couldn’t have been available on Earth at the time life first began, because three billion years ago, the surface of the Earth had very little oxygen, but Mars did.

"It’s yet another piece of evidence which makes it more likely life came to Earth on a Martian meteorite, rather than starting on this planet."

Early Mars is also thought to have had a drier environment, and this is also crucial to its favourable location for life's origins.

"What’s quite clear is that boron, as an element, is quite scarce in Earth’s crust," Prof Benner told BBC News, “but Mars has been drier than Earth and more oxidising, so if Earth is not suitable for the chemistry, Mars might be.

"The evidence seems to be building that we are actually all Martians; that life started on Mars and came to Earth on a rock," he commented.

"It’s lucky that we ended up here, nevertheless - as certainly Earth has been the better of the two planets for sustaining life. If our hypothetical Martian ancestors had remained on Mars, there may not have been a story to tell."
