The idea of molecular clock genes has been studied for decades, but the hypothesis remains a controversial topic in evolutionary biology. Why do you think that is the case? What are three questions you still have about the use of molecular clocks?​

Sagot :

Answer:

I think thats the case because a lot of scientists have evidence to back it up but some scietntists have other evidence for it not to be true and its just a back and forth problem.

1. Why does It assum that all changes in amino acid sequence are random and are not affected by natural selection?

2. Why do they use these clocks when our fossil record only goes back 550 million years ago?

3.  What age range is appropriate for molecular clock dating analysis?

Explanation:

I don't know if this is right by this what I put. Have a good day!

The idea of a molecular clock gene remains a controversial topic because scientists have different opinions on genes mutations occurring at constant rates.

What are molecular clock genes?

Molecular clock genes are genes which are assumed used as molecular clocks to determine the age of living organisms.

The idea of a molecular clock gene remains a controversial topic because different scientists have different opinions on if a changes in DNA over time can actually be used to determine the age of organisms,

Three questions that can be asked is this:

  1. are mutations in DNA really random at all times?
  2. do mutations really occur at a constant rate?
  3. do the same mutations occur in the same species to the same extent?

Therefore, until all scientists agree base on evidence, molecular clock genes remains a controversial topic.
