A significant shift in the environmental conditions over a very short period of time caused most groups of dinosaurs to become extinct because of their inability to adapt fast enough. This allowed for a variety of niches to open providing current organisms new opportunities. Mammals were one group of organisms that took advantage of this environmental change, filling niches that were unoccupied and eventually developing new species that were specifically adapted to their particular environment. Which of the following is a term that most correctly describes this process?A. Adaptive radiationB. GradualismC. Convergent evolutionD. Genetic drift

Multiple sequence alignment is a method that can be used to compare three or more biological sequences to determine homology and evolutionary relationships between species. This is done by selecting a target protein or DNA sequence (consensus) and comparing it across other species sequences. Conservation is a statistical analysis that describes how much the target sequence is observed across the selected group of species. A higher conservation score indicates that the protein or gene is more ancient or more critical across species. Construct a cladogram using the multiple alignment of a protein sequence found below.
