What if? suppose a molecular clock dates the divergence of two taxa at 80 million years ago, but new fossil evidence shows that the taxa diverged at least 120 million years ago. explain how this could happen.

The gene/genes which was applied for the molecular clock determination may have evolved at a slow pace in these two taxa when compared to species used to calibrate the clock; this will lead to the clock underestimating the time of divergence of the two taxa apart from each other.

the correct answer is: d. the saltine and pretzel are made of flour, yeast, and baking soda, and salt. the pecan contains no flour but it does contain fats. the pecan is a nut that can be consumed as a healthy snack. first of all, pecans are a source of fat (monounsaturated fat), but they provide less fat than some other nuts. pecans are a rich source of dietary fiber, manganese magnesium, phosphorus, thiamin, vitamin e…
