What molecule do scientists believe came first in the evolution of life on Earth?
Scientists believe that the molecule that came first in the evolution of life on Earth is RNA (ribonucleic acid).
When do scientists believe life originated on Earth?
Scientists believe life originated on Earth around 3.5 to 4 billion years ago. This is based on fossil evidence of simple life forms found in rocks dating back to that time period and the presence of key molecules necessary for life in early Earth environments.
Why do scientists think life began in africia?
Scientists believe life may have originated in Africa because the continent has a diverse range of habitats and a long history of supporting life. Fossil evidence suggests that early human ancestors originated in Africa, leading to the idea that life itself may have emerged there as well. Additionally, Africa's unique geology and climate are believed to have provided favorable conditions for the development of early life forms.
Where do scientists find evidence of early human life?
East Africa
Why do scientists suspect life on mars might have been possible at one time?
I believe it is water and life.
How do scientist think plant life came to earth?
They do not think plant life 'came' to Earth. They believe it evolved here.
Where do scientists believe the chemical evolution occurred?
Scientists believe that chemical evolution occurred in the early Earth's oceans, where simple molecules combined and formed more complex ones through processes like lightning, UV radiation, and undersea vents. These conditions allowed for the formation of organic compounds, leading to the development of life over time.
Which substance do scientists think was critical to the rise of life on early earth A amino acids B water C organic material D oxygen?
Scientists believe that water (B) was critical to the rise of life on early Earth. It provided a stable environment for chemical reactions and facilitated the formation of organic molecules. While amino acids and organic material are essential for life, water's role as a solvent and medium for biochemical processes was fundamental in creating the conditions necessary for life to emerge.
Is living thing is possible in Mars?
No, but scientists believe that there could have once been life on Mars.
What planet do scientists believe life may once have existed on?
mars. now tell me why they think that?
Do scientists believe that liquid water us essential to life?
Yes, as far as we know.
Where do scientists believe chemical evolution occcured?
Scientists believe that chemical evolution, or the formation of complex organic molecules from simpler compounds, occurred in the early Earth's oceans, hydrothermal vents, or deep-sea environments. These environments provided the necessary conditions, such as energy sources and a variety of chemical compounds, for the spontaneous formation of complex molecules that eventually led to the origin of life.
