Question

A) Dr. Schneider did a study on the food choice of garden snakes in a single regurgitated (i.e, she m selected snakes, 72 of which produced a mouse, not yet digested. She measured the tails of the mice, with the average tail length at 4.7 centimeters. She then randomly selected 100 living mice in the same field, and measured their tail lengths. The average tail length of her living mouse sample was 2.3 cm. What does this observation suggest about organism fitness and evolution? B) Dr. Schneider then tells Dr. Ross of her findings, and Dr. Ross recalls a study he had read suggesting that longer tails are more successful in mouse mating, making mice with longer tails more reproductively fit. Based on Dr. Schneider's findings, what is a possible evolutionary limitation preventing mice tails from getting longer and longer? field. She h. ade the snakes vomit up their stomach contents) 100 randomly

Explanation / Answer

A) Mouse with longer tail has higher probability of being ended up as a prey to garden snake than the mouse with shorter tails. So, over the course of evolution, mouse with shorter tail has higher chances of survival.

B) The evolutionary limitation that prevents the mouse tails from becoming longer is the higher probability of mouse with longer tail being ended up as a prey to snakes.
