What factors made evolution move slowly for the first two billion years of life on earth?
Two factors, both related to the availability of energy and presence of mutagens.
First, the sun was much dimmer two billion years ago; it provided about 30% less heat, and less radiation. Second, there was very little free molecular oxygen in the atmosphere. Most organisms were anaerobe. Oxygen-based metabolisms are much more energetic than anaerobe metabolisms, and on top of that, oxygen-based chemistry provides much more free radicals, which act as mutagens. So life back then was slower, as well as mutation rate.

What factor made evolution move very slowly for the 2 billion years of life on earth?
One factor that contributed to the slow pace of evolution over the 2 billion years of life on Earth was the limited genetic variation and the lack of mechanisms for rapid adaptation. Without mechanisms such as sexual reproduction or mutations, organisms were constrained by their existing genetic blueprints, which limited the speed at which significant evolutionary changes could occur.
What factor made evolution move very slowly for the first two billion years of life on earthAsk us anything?
The slow pace of evolution in the first two billion years of life on Earth was due to limited genetic diversity and the lack of complex mechanisms for genetic variation. As life forms were simple and unicellular, mutations were rare and the environment was relatively stable compared to later periods, which slowed down the process of natural selection and evolution.
How do genetic variation and environmental factors influence evolution?
Genetic variation drives evolution by providing the raw material for natural selection to act upon, allowing organisms to adapt to changing environments. Environmental factors can influence which traits are favored, shaping the direction of evolution. Together, genetic variation and environmental factors contribute to the diversity of life on Earth through the process of evolution.
What are the factors in the evolution and diversity of life on earth?
Some factors contributing to the evolution and diversity of life on Earth include genetic mutations, natural selection, environmental changes, geographic isolation, and species interactions. These factors influence the adaptation and survival of organisms, leading to the development of new species and increased biodiversity over time.
How long the prokaryotes populated Earth before the evolution of eukaryotic cells which are more complex?
Prokaryotes populated Earth for about 1.5 billion years before the evolution of eukaryotic cells, which are more complex. Eukaryotic cells are believed to have evolved around 2 billion years ago through a process called endosymbiosis.

How long has evolution been going on?
Evolution has been occurring on Earth for over 3.5 billion years. The process of evolution is ongoing and has led to the diversity of life forms that we see today.

When was the earth created according to evolution?
Evolution does not make any regard to the origin of the earth. It only deals with the development of existing life. Geological and physical sciences teach that Earth formed approximately 4.54 billion years ago.
What factor made evolution moves very slowly for the first two billion years of life on earth?
Anaerobic metabolisms and asexual reproduction
How old the earth today?
Evolution says the earth is 4.54 billion years old and the universe 13.77 billion years old. The Bible says it is 6019 years old.
The three major factors though to control the evolution of the earth?
weather, movement of plates,
Did evolution play during Cenozoic era?
Of course. Evolution has happened ever since life first came into existence on Earth, some 3.5 billion years ago.
What would the earth be like if this creature - man - were to become extinct?
If the creature you refer to is man, its a question of when not if. When we're gone, bacteria will slowly break down the poisons we leave behind,and evolution will continue.Biodiversity will increase again.There's still about 4 billion years to go.Man is only a fleeting moment in the colossal age of the earth.
When did scientists believe that chemical evolution occurred?
Scientists have believed that chemical evolution occurred about 4 billion years ago, shortly after the formation of the Earth. This process is thought to have led to the development of the first life forms on our planet.
What is the name of the earth evoulution of Eevee?

How many mass extinctions have occurred in the past 4 billion years on earth?
There have been five mass extinctions in the past 4 billion years on Earth. These events resulted in the widespread loss of species and fundamentally reshaped the evolution of life on our planet.
