Explain how biochemical evidence, including dna, scientists to learn about early life on earth

Biochemical evidence like fossils, anatomical comparisons between organisms, molecular tests, continental drift, similarity traits explain the evolution and early circumstances in which life started on the Earth.

The following are the evidences which helps scientists to learn about early life on Earth:

Therefore, biochemical evidence help researchers in learning about the early life on the Earth.

Biochemical evidence such as fossil records, geological evidence, comparative anatomy, similar selective pressures, and molecular evidence all prove evolution and indicate the conditions in which early life resided on earth.

Explanation:

Fossil records- transitional forms of modern and ancient creatures imply the time periods of evolution and the environmental factors which forced those changes.

Geological evidence- (e.g. continental drift) can reveal the geographic conditions of ancient environments and the resulting interactions of different life forms.

Comparative anatomy- connects closely related species through similar physical structures.

Selective pressures- different organisms exhibited similar behavioral changes, indicating common ancient geological pressures.

Molecular evidence- organisms with related DNA prove ancient connections between species.

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).
