Life on Earth evolved from bacteria to humans through a process of natural selection. This process involved the development of self-replicating molecules that eventually evolved into more complex organisms.
Early life
The first unicellular organisms emerged between 3.6 billion and 2.7 billion years ago.
These organisms gave rise to bacteria and archaea, which lack a nucleus and other organelles.
Some scientists believe that the first life forms may have originated in hydrothermal environments, such as hot springs and deep-sea vents.
Eukaryotic cells
Eukaryotic cells, which include human cells, evolved from bacteria about two billion years ago.
One theory is that eukaryotic cells evolved from a symbiotic relationship between two bacteria.
Eukaryotic cells are larger than prokaryotic cells, such as bacteria.
The Last Universal Common Ancestor (LUCA)
LUCA is the hypothetical ancestor of all modern cellular life.
LUCA shared many characteristics with modern life, including:
The same amino acids used to build proteins
The energy currency ATP
The ribosome, which uses DNA to construct proteins
DNA as the storage medium for information
Evolution of more complex organisms
As conditions became more favorable, more complex organisms began to evolve.
These organisms include protists, plants, animals, and fungi.
Other topics related to this.
Many people believe humans evolved from apes since we share 98% of our DNA with them. Etc
People also believe that God created us in his image.
