The most popular scientific theory states that earth was once a Porto planet, a planet that is like a baby. a large asteroid [left overs from the sun] soon gained gravity that pulled more asteroids towards it. in a few million years, the large asteroid will become red and be filled with lava. volcanoes erupted that formed clouds with water then water filled today's ocean. the rest of the volcanoes made large islands that became Pangaea then Pangaea becomes today's continents. of course earth developed an atmosphere then clouds formed. the first animal was a bacterial that released methane in to the atmosphere. later oxygen releasing Bacterial developed and killed the methane releasing bacterial. then fish evolved, then land animals [small] then dinosaurs, then mammals, the probably Porto humans or early humanly creatures, then homosepicans, then caveman, then today's humans.

What gas became part of Earths atmosphere mainly as a result of the evolution of life-forms?

Oxygen became part of Earth's atmosphere mainly as a result of the evolution of life forms, particularly through photosynthesis by early cyanobacteria and plants. This process involved converting carbon dioxide into oxygen as a byproduct, leading to the oxygen-rich atmosphere we have today.


Why do you think scientists study earths interior?

Scientists study Earth's interior to better understand the planet's composition, structure, and dynamics. This helps in predicting natural disasters like earthquakes and volcanic eruptions, as well as in understanding processes like plate tectonics and magnetic field generation. Studying the Earth's interior also provides insights into the planet's history and evolution.


Earths early atmosphere was changed dramatically by the evolution of?

photosynthetic organisms, like cyanobacteria, which produced oxygen as a byproduct of photosynthesis. This led to the increase in atmospheric oxygen levels, changing the composition of Earth's early atmosphere.


What is earths Precambrian atmosphere?

The Earth's Precambrian atmosphere was primarily composed of carbon dioxide, methane, ammonia, and water vapor. It lacked oxygen and had higher levels of greenhouse gases compared to the present atmosphere. This environment supported the evolution of early life forms such as bacteria and algae.


How did changes in earths environment affect the evolution of life?

Changes in Earth's environment, such as changes in temperature, atmospheric composition, and sea levels, have greatly influenced the evolution of life. These changes have created selection pressures, leading to the extinction of some species while promoting the adaptation and diversification of others. Life forms that were able to adapt to changing environmental conditions were more likely to survive and thrive, ultimately shaping the biodiversity we see today.

Micro-evolution is not only a part of macro-evolution, it is the same mechanism as macro-evolution. Macro-evolution includes speciation, as a result of continuing micro-evolution.

What is the difference between evolution and theories of evolution?

Evolution is the process by which species change over time through natural selection. Theories of evolution, such as Darwin's theory of evolution by natural selection, are explanations for how evolution occurs and the mechanisms driving it. In essence, evolution is the phenomenon, while theories of evolution are the explanations for how it happens.
