When selecting among multiple possible phylogenetic trees that fit our data, we commonly use the principle of _____, which means
nordsb [41]

a. parsimony; simplest; fewest

When selecting among multiple possible phylogenetic trees that fit our data, we commonly use the principle of <u>parsimony</u>, which means we choose the <u>simplest</u> possible hypothesis. In phylogenetic analysis, that means selecting the tree that represents the <u>fewest</u> evolutionary changes or mutations.

Explanation:

Phylogeny describes the evolutionary history of on organism or group of organisms.  

A phylogenetic tree structure is used to describe the relationship between various organisms which have originated from common ancestors.  

The Principle of Parsimony is best applied while constructing phylogenetic tree.  

This principle emphasizes on simple observations on a phylogeny which requires only few changes or variations which explain for the difference between the phylogenic sequences.  

This tree structure will only have few specific genetic variations or mutations or evolutionary changes which took place through new appearance of a trait or disappearance of an existing trait.

REY [17]

<u>Answer:</u>

Charles Darwin’s study of evolution predicts that genetic evidence would show that all organisms share a common ancestor.

Option: (B)

<u>Explanation: </u>

  • Through his "theory of evolution", Darwin found that the species exist and new species form based on natural selection.
  • He studied the animals and birds in Galapagos island for his evolution theory.  

<u>The four key points of Darwin's Theory of Evolution:</u>

  • individuals of any species are not identical;  
  • genes are passed from one 'generation' to another;
  • more offspring are born than can survive;  
  • only the 'survivors of the competition' for the resources will reproduce.
