One hypothesis for the Cambrian explosion was an increase in predator-prey relationships. It is thought that the resulting co-evolution of predator and prey may have been a factor in the rapid speciation of animals seen during this time. What findings in the fossil record would most support this? Group of answer choices a. increased incidence of larger-bodied animals b. increased incidence of sessile animals c. decreased incidence of animals with bilateral symmetry d. increased incidence of animals with radial symmetry e. increased incidence of shells, bony plates, spines, and/or claws

What is an example of evolutionary mismatch in modern day humans?    A. Evolutionary mismatch is not a real concept.   B.

Fruits and vegetables were disadvantageous for early humans to eat, but they are healthy for modern humans.    D. Fatty and sugary foods were advantageous for early humans to eat, but they are overly abundant in modern times and contribute to obesity.
