You are a scientist who notices great similarity between the spines of a hedgehog and the spines of a porcupine. When you study
their genetics, however, you notice that the set of genes that code for hedgehog spines is a different set of genes than the set that codes for porcupine spines. You decide this must be an example of______________.a. convergent evolutionb. divergent evolutionc. coalescent evolutiond. unifying evolution
The correct option is <em>A. convergent evolution</em>
Explanation:
The phenomenon of evolution explains how different species might have common ancestors. This phenomenon explains that genetic variations might have led to the birth of different species from a common ancestor.
Convergent evolution can be described as a type of evolution in which similar features or traits can be observed in organisms although they may not have any genetic sequence in common. For example, sharks and dolphins look similar but they have huge differences in their genomes.
When the barge enters the northern most part of the river, the southward current is 0.67 m/s. How will the barge be affected? The barge will move slower. The direction of the barge will change.
