A recent rock discovery could completely rewrite history about life on Earth, scientists say

The structure of these fossils indicates the likelihood of alien life.

Awọn onimo ijinlẹ sayensi gbagbọ pe wọn ti ṣe awari awọn fossils ti atijọ julọ ni agbaye, eyiti o le wa sẹhin o kere ju ọdun 3.75 bilionu. Ti eyi ba jẹ ẹri, o le pe sinu ibeere ero-aye wa lori Aye ati yi itan pada.

Dominic Papineau, alajọṣepọ alamọdaju ti geochemistry ati astrobiology ni University College London, ṣe awari awọn fossils ni ariwa Quebec, Canada (UCL). Papineau ṣe awari eyi ni irin-ajo kan si Quebec's Nuvvuagittuq Supracrustal Belt ni ọdun 2008.

Ni 2017, aṣoju ẹlẹgbẹ ati awọn oniwadi UCL ti tu nkan kan silẹ ni Iseda ti o sọ pe awọn filaments kekere ati awọn okun ti a rii ninu awọn apata wọnyi fihan pe wọn le ti ṣe nipasẹ awọn kokoro arun.

Wọn tun ṣe akiyesi agbara ti awọn fọọmu igbesi aye agbalagba ju ti eniyan ti ro tẹlẹ. Nigba ti won ti so wipe awọn apata boya 3.75 bilionu ọdun atijọ, nibẹ ni akude akiyesi pe won le jẹ Elo, Elo agbalagba. Awọn oniwadi beere boya wọn le jẹ ọdun 4.2 bilionu. Iyẹn yoo jẹ aigbagbọ.

Oun ati ẹgbẹ rẹ ṣe atẹjade iwadii kan ni Awọn ilọsiwaju Imọ-jinlẹ ti o ṣalaye awọn iwadii 'pataki' ti ṣafihan 'orisirisi ilolupo eda microbial lori Earth akọkọ ti o le jẹ aṣoju lori awọn ara aye aye miiran, pẹlu Mars.'

Lakoko ti o n ba Igbakeji sọrọ, Papineau tun sọ pe: “Iwoye, o jẹ igbadun pupọ nitori kii ṣe pe a ṣe agbekalẹ ọna imọ-jinlẹ nikan pẹlu awọn laini ominira lọpọlọpọ ti ẹri lati teramo ipilẹṣẹ ti ibi, a tun yọkuro awọn aati abiotic ti a mọ.”

“Awọn microfossils wọnyi le wa nitootọ lori awọn oju aye aye atijọ miiran nitori ti ipilẹṣẹ ti igbesi aye ba gba akoko kukuru bẹ lati dagbasoke, ati pe o ni ipele eka yii, lẹhinna iyẹn mu ọpọlọpọ awọn ibeere imọ-jinlẹ tuntun dide nipa iṣeeṣe ti igbesi aye le ni. dide o si fi iru awọn ami-ami wọnyi silẹ”.

“O ṣẹda ọpọlọpọ awọn aye tuntun lati Titari aago sẹhin fun ipilẹṣẹ ti igbesi aye ati lati wa ni pataki fun iru awọn nkan wọnyi lori awọn aye aye miiran.”

The structure of these fossils, according to the associate professor, indicates the likelihood of alien life and might be utilized as a doorway into the study of extraterrestrials.

"Ni kedere Mo n mu nkan iyebiye diẹ mu," O sọ. “Wọn jẹ awọn ohun elo ti o ti kọja ti o jinna pupọ. Nítorí náà, lọ́nà kan, ó jẹ́ onírẹ̀lẹ̀ gan-an nítorí pé èmi ni ènìyàn àkọ́kọ́, ẹranko àkọ́kọ́, ẹ̀dá àkọ́kọ́ lórí ilẹ̀ ayé, láti rí àwọn nǹkan wọ̀nyí àti láti mọ ohun tí wọ́n jẹ́.”

Ṣaaju awọn awari wọnyi, ni ibamu si Oludari Iṣowo, awọn apata atijọ julọ titi di oni jẹ awọn fossils bilionu 3.5 ti a rii ni iwọ-oorun Australia.
