Summary Introduction

To determine: The probable history of the evolution of diet in the given clade of birds.

Introduction: Evolution is a natural phenomenon by which new species with certain distinct traits evolve from primitive ones. Adaption has a highly active role in evolution. Certain species may have a common ancestor, while others may have a different ancestor. Morphological and anatomical features provide information about the evolutionary history of an organism.

In a phylogenetic analysis of several bird species, a researcher uses a species of reptile as an outgroup. Which of the following is the main reason for including an outgroup in the analysis? To identify ancestral traits shared by the bird species To determine the overall genetic diversity of the bird species To establish a new monophyletic group including both bird and reptile species To analyze the convergent evolution of bird and reptile species
Four Caribbean islands with similar environmental conditions have three different species of anole lizards with specific ecological morphotypes.  Lizards Morphotypes Grass lizards Long tails Canopy lizards Large toe pads Twig lizards Short legs Researchers devised two phylogenetic trees to represent two different hypotheses about how the lizards may have evolved. The first hypothesis is that the different body types evolved repeatedly and independently of each island. The second suggests that each morphotype evolved once and spread to different islands.   Which of the following statements best explains which type of data the researchers should use to test these two hypotheses, and which phylogenetic tree correctly shows the evolutionary relationships among anoles? Analyzing DNA samples from the anoles would likely show that phylogenetic tree B is correct since it is likely that each body type evolved once and spread to different islands. Analyzing the…
