A classification method that uses shared traits of organisms such as the presence or absence of jaws, bones, lungs and limbs, as shown in the figure below, to predict phylogeny is called
a. paleontolog
b. archeology
c. cladistics
d. Benomics
e. convergent evolution
Ans. Cladistics
Explaination: Cladistics deals with characterization of organisms on the basis of shared traits like presence or absence of limbs,jaws etc. Paleontology deals with the study of fossil animals and plants. Archaeology deals with the study of past human civilisation through remains such as coins, buildings,inscriptions etc. left by ancient people. Genomics deals with the study of structure and function and editing of genomes. In covergent evolution, there is development of similar traits on unrelated species lines.

Skin color in humans is an example of an evolutionary trade-off: a situation where a trait that is an advantage in one context is a disadvantage in a different context. Darker skin protects DNA from damage due to ultraviolet radiation (an advantage) but makes it harder for the body to produce vitamin D (a disadvantage). Based on what you’ve learned, which of the following describe other examples of evolutionary trade-offs? Select all that apply.
A) Genetic variations that protect people from malaria also cause the blood diseases thalassemia B) Some garter snakes have mutations that make them resistant to a toxin in their prey however snakes with this mutation move more slowly and are not as good at hunting prey C) The alleles that caused a loss of body hair allowed humans to keep cool in hot environments. This in turn helped humans walk and run long distances to hunt large animals D) The common Mormon butterfly is not toxic to birds and other predators. Some common Mormons have genetic variations that make them resemble toxic butterflies, which deters predators. in places without predators, common Mormons with these variations don't live as long as other common Mormons.
