Which of the following methods was considered the most accurate for determining the age of fossils?

The age of fossils was traditionally determined by radio-carbon dating and other methods involving radioactive elements found in the rocks. More precise methods currently used for determining the evolutionary time of different groups of organisms include:

In evolution,studies can be conducted at the molecular level. For example,proteins found in the blood of humans and apes are similar. The base sequences in nucleic acids and amino acid sequences in proteins are similar in related organisms. What do all these examples specifically refer to?

Which of the following correctly describes homologous structures?

The forelimbs of a cat and a lizard are used for walking. The forelimb of a whale is used for swimming,and the forelimb of a bat is used for flying. These are examples of:

State the modifications of forelimb in animals as an example of homology.
