Origin theories of life

"Life formation on the earth may have been taken

place due to supernatural or divine forces". This statement belongs to:

• Theory of biochemical evolution

• Simple begginings

• RNA world

• Special creation

"Life formation did not take place on earth. It took place somewhere else in the space or on any other planet and carried to the earth.". This statement belongs to:

• Theory of biochemical evolution

• Extraterrestrial origin

• RNA world

• Spontaneous origin

This experiment (picture) was made by Franceso Redi to test the theory of:

• Theory of biochemical evolution

• Chilly start

• Electric spark

• Spontaneous origin

"Life could have arisen through a series of organic chemical reactions that produced ever more complex

biochemical structures. They proposed that common gases in the early Earth atmosphere combined to form simple organic chemicals, and that these in turn combined to form more complex molecules. Then, the complex molecules became separated from the surrounding medium, and acquired some of the characters of living organisms. They became able to absorb nutrients, to grow, to divide (reproduce), and so on.". This statement belongs to:

• Theory of biochemical evolution

• Community clay

• RNA world

• Spontaneous origin

"Instead of originating from complex molecules like RNA, DNA, life might have begun with small and simple molecules interacting with each other in cycles of reactions. These reactions might have been change a simple capsule to cell membranes and over time

more complex molecules or cells.". This statement belongs to:

• Theory of biochemical evolution

• Community clay

• Simple beginnings

"Life on Earth began with simple RNA molecule that could copy itself without help from any other molecule.". This statement belongs to:

• Theory of biochemical evolution

• Chilly start

• Electric spark

• RNA world

"Ice might have covered the oceans 3 billion years ago, as the sun was three times less luminous than it now. This layer of ice, possibly hundreds of feet thick, might have protected fragile, organic compounds in the water below from ultraviolet light and destruction from cosmic

impacts". This statement belongs to:

• Theory of biochemical evolution

• Chilly start

• Deep sea vents

• RNA world

"This theory suggests that life arose deep in the

ocean with hydrogen rich molecules. Their rocky nooks could then have concentrated these molecules together and provided mineral catalysts for critical reactions.

Alkaline fluids from the Earth’s crust flow up towards the more acidic ocean water, creating natural proton concentration differences remarkably similar to those powering all living cells.". This statement belongs to:

"The first molecule of life, hydrocarbon, might have

met on some surfaces that might not only have concentrated these organic compounds together but also helped organize them into patterns much like our genes". This statement belongs to:

• Theory of biochemical evolution

• Community clay

• Chilly start

• RNA world

"First form of life came into existence following one spark or on one particular spark day. The other version argues that life came into existence, or rather emerged, following prolonged sparking rather one specific spark. Electric emissions can generate amino acids and

sugars from an atmosphere loaded with water, methane, ammonia and hydrogen". This statement belongs to:
