Scientists can see th fossils and the living organisms.
Fossils are proof of organisms that lived long ago
Trace Fossil

The preserved remains of animals of evidence of their existence are Fossils Fosssils that provide evidence about the past are called trace fossils.
yo but holeLimestone deposits that began as coral reefs provide evidence of how plate motions have changed Earth's surface. These deposits also provide evidence of past environments.
We don't know that they do. Evidence of running water some time in the past has been found on the surface of Mars, but as yet no direct evidence of the past or present existence of micro-organisms.
vestigial structure
Limestone deposits that began as coral reefs provide how plate motions have changed Earth's surface. These deposits also provide evidence of past environments.
Vestigial structures are anatomical features that have lost their original function in an organism but are still present. These structures often have similarities to functional structures in related organisms, suggesting a shared evolutionary history. By studying these vestigial structures, scientists can infer how organisms have changed over time through the process of evolution.
changes in the environment e.g. the place, temperature, climate.
Darwin's theory of common descent states that all organisms evolved from past organisms.
a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
