Minnows are mainly carnivorous, eating insects and other small animals. However, herbivory has evolved independently in minnows several times. What changes in digestive structure and function are associated with the evolution of herbivory? Why did the researchers compare relative gut length instead of absolute gut length?

Video transcript

Hello, everyone here We have a question that tells us a researcher measured the total get length of two fish species X. And Y. Of comparable body size is found in the Panamanian forest streams. And the question is what is the most likely observation for the total gut length and species X and Y. If they are herbivores and carnivorous respectfully? So Species X. Is our herb divorced one, so we want it to have a higher got length and species wide because species wise carnivorous and the gut length is higher in herb divorce because they have to digest cellulose. So our answer here is a Species x equals 110 cm and species y equals cm. Thank you for watching. Bye.
