Answer: (b)
The population of fish with pelvic spines that arrived in the lake at time B evolved a reduced pelvis over time (beginning at time C)
Reduction of pelvic spines have been seen to be be advantageous where grasping predators poses threat.
Bell and collaborators painstakingly documented a population of fossil sticklebacks from an ancient freshwater lake over...
bio lab palentology questions that is the entire lab i did not leave anything out ~ Lab 11: The Witte il An Introduction to Paleontology 1.

What conclusion can you draw from your graph in Experiment 1? One of the functions of pelvic spines in the ocean is to protect stickleback from larger fish predators. Based on this knowledge, what might be a possible explanation for the differences in pelvic spines between Bear Paw Lake and Frog Lake sticklebacks? What is the relationship between age and position of sediment layers in the Nevada lake quarry? How would you test whether the ancient Nevada lake contained predatory...
