Question

How did those first eukaryotic cells get here? What are your ideas concerning the evolution of the first eukaryotic cells?

Do not concern yourself with how life first formed, rather just concern yourself with how eukaryotic cells first evolved. Please look at this from a scientific standpoint and not a religious point of view.

Answer 1

Answer:

During evolution , simple molecules combined and reacted to form proteins and nucleic acids. These formed RNA, DNA and enzymes. These developed to form prokaryotic cells. These prokaryotic cells came into symbiotic relationship with other Microbes which evolved to form structures called cell organelles. The increased amount of energy requirement led to evolution of mitochondria and chloroplasts developed to fulfill the requirements of food source. These led to development of plant cells carrying photosynthesis.

Likewise , other organelles developed according to cellular needs. Ribosomes for protein formation, vacuoles for storage of food and water,and others.

Nuclear membrane formed to protect the DNA which folded to form chromatin material . This provided better functioning and protection of genetic material.

This is how eukaryotes would have developed from simpler molecules and associated to form complex living organisms.
