What are molecule clocks?

Molecular Clocks- are models that use mutation rates to measure evolutionary time.


Why are only neutral mutations useful for molecular clocks?

Only neutral mutations are useful for molecular clocks because they accumulate in the DNA of different species at the same rate, while other mutations do not.


What do molecular clocks use to measure evolutionary time?

mutation rates


Biological evidence of the age of the earth includes?

fossil records, comparative anatomy, and Molecular clocks.

Biologists use molecular clocks to try to measure?

Generally, a molecular clock is used to describe the rate of molecular change over time that tells you when two species, or taxa, have diverged.


Comparison of DNA to determine how long different species have been evolving independently can be done using?

molecular clocks


What is the main idea behind the model of a molecular clock?

The molecular clock is used to estimate the time of occurrence of events called speciation and radiation. The molecular data used for such calculations is usually nucleotide sequence for DNA or amino acid sequences for proteins. In other words, a protein is known as a molecular clock because it changes over time.


Why are there many molecular clocks in a genome instead of just one?

This occurs because some genes accumulate mutations faster than others.


Why are there many molecular clocks in one genome instead of just one?

This occurs because some genes accumulate mutations faster than others.


Is it implications on or implications for?

for is the correct choice


How do rates of mutation power molecular clocks?

The number of neutral mutations distinguishing two species enables measurement of the length of time since the species diverged from a common ancestor.
