Origin of Life Conundrums Require A Divine Designer | Cold Case Christianity https://buff.ly/X0U2VPD #IntelligentDesign #evidence #science #abiogenesis #apologetics
The last universal common ancestor lived off #hydrogen gas and carbon dioxide, boasted a genome as large as that of some modern #bacteria, and already had an immune system
Its genomic complexity suggests that it was one of many lineages living about 4.2 billion years ago, a turbulent time early in Earth’s history and long thought too harsh for life to flourish.
#Life evolved from a simple replicator into something resembling modern microbes very quickly.

Ancient #Earth was nothing like our current home.
It was a much more hostile place; rich in metallic iron with an #atmosphere containing hydrogen and methane.
These molecules contain an important clue to how #life was initially formed.
When exposed to solar #ultraviolet radiation, they undergo a chemical reaction that produces organics: precursors to essential biomolecules, such as amino acids and nucleic acids.

There're two main theories about origin of🌱 #Life on Earth: #Aristotle's 🧬⚡#aBioGenesis and Hermann Richter's🧬☄️#PanSpermia (1865)
If #PanSpermia was right and #Mars was capable of supporting life, how come there is no life on #Mars?

The nature of the last universal common ancestor (#LUCA) have been the subject of vigorous debate across diverse disciplines.
Age estimates for LUCA are usually based on the fossil record, varying with every reinterpretation while #metabolism has proven equally contentious.
New results indicate that LUCA lived ~4.2 Ga ago and had a genome of at least 2.5 Mb, encoding around 2600 #proteins.

• Solving the mystery of abiogenesis could provide insights into the conditions necessary for life and the potential for life elsewhere in the universe. #OriginOfLife #Abiogenesis #LifeOnEarth
Synthesis and stability of biomolecules in C-H-O-N fluids at extreme pressure-temperature conditions
Within a few billion years atoms formed, then stars formed from atoms, galaxies formed from stars and gas, our Sun formed, soon followed by our Earth, about 4.6 billion years ago.
#Abiogenesis is the natural process by which life arises from non-living matter, such as simple organic compounds. The prevailing scientific hypothesis is that the transition from non-living to living entities on Earth was not a single event, but a process of increasing complexity.

What implications does the #flare frequency have on #ozone depletion and #abiogenesis in #exoplanets orbiting M dwarfs?
Even when #stars have a sufficiently high rate of energetic flares, such that they are likely to have a positive impact on abiogenesis on Earth-like #planets, there might simultaneously be significant ozone depletion.

#DidYouKnow: In biology, #Abiogenesis or the origin of life is the natural process by which life has arisen from non-living matter, such as simple organic compounds.
Stages in the origin of life range from the well-understood, such as the habitable Earth and the abiotic synthesis of simple molecules, to the largely unknown, like the derivation of the last universal common ancestor (LUCA) with its complex molecular functionalities. (1/2)
