The first life on Earth is believed to have appeared around 3.5 to 4 billion years ago. These early organisms were likely simple single-celled prokaryotes, such as bacteria and archaea, which thrived in extreme environments. Fossil evidence, including stromatolites, suggests that these microorganisms were among the earliest forms of life on the planet.

What is an organism's life span?
An organism's life span is the maximum amount of time it is expected to live. Life spans vary greatly between different species, ranging from a few hours for some insects to over 100 years for certain mammals like whales and elephants. Environmental factors, genetic influences, and lifestyle can also affect an organism's life span.
What is a trace of long dead organism?
A trace of a long dead organism could be a fossilized imprint, track, or remains left behind in sedimentary rock. These traces provide valuable information about the organism's existence, behavior, and environment in the past. Scientists study these traces to learn more about ancient life on Earth.

What is the process of change that occurs during an organism's life producing a more complex organism?
The correct answer is GROWTH and/or DEVELOPMENT... one of the characteristics of life... Evolution is the change in a species over a long period of time.... you would not notice these changes in an organism's life. ===================================== When an organism becomes more complex during its own life, that is called growth or growth and development.
