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?​

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 answer is b)3/8x+1

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
