Biological evidence of the age of the earth includes _____.


radioactive dating of rocks

fossil evidence

comparative anatomy

molecular clocks

gradual processes of rock formation

Verified Answer :

Answer: comparative anatomy

fossil evidence

molecular clocks

Explanation:

Comparative anatomy: It is the study of determining the differences and similarities in the structural anatomy of different species. It helps in determining the phylogenetic relationship among the primitive and modern organisms. Thus the evidences obtain from such studies can be used to determine the age of earth.


Fossil evidence: The fossil is trace evidence of dead animals or plants that are preserved under the sedimentary rocks. The evidences of traces can be looked for evolutionary development. This development can be compared with the history of the earth.


Molecular clocks: The average rate at which the genome of the species accumulates the mutations that can be used to examine the divergence of evolution. The rate of evolution can be examined to know how old the species was hence, it will help in determining the age of Earth.

Answer:

-Fossil evidence


-Comparative anatomy


-Molecular clocks


Biological evidence of the age of the earth includes fossil evidence, comparative anatomy, and molecular clocks.


Explanation;


-Fossils are critical tools in science because they give us clues to the types of plants and animals that lived on Earth in the past.There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined.


-Comparative anatomy is an important tool that helps determine evolutionary relationships between organisms and whether or not they share common ancestors. However, it is also important evidence for evolution. Anatomical similarities between organisms support the idea that these organisms evolved from a common ancestor.


-Scientists can use relaxed-clock methods to deal with variation in the rate of the molecular clock. By measuring the patterns of evolutionary rate variation among organisms, they can also gain valuable insight into the biological processes that determine how quickly the molecular clock ticks.
