Answer: False
Explanation:
The teeth of mammals do not have the similar function to perform. They have different types, number and sizes of teeth that are equipped to perform different functions.
Example: Human beings have incisors,canines, molar and premolar. The incisors are used to cut the food and hold the food.
The canines are use to tear hard food such as meat. The molars and premolars are used to grind the food.
Hence, the given statement is false.

Maximum Thrift is a method / philosophy that considers the shortest tree (in number of transformation steps) the best hypothesis about the phylogenetic relationship of a given set of terminals. Transformation step is the cost attributed to the change of character state in a given branch of the tree, be it the change from one nucleotide base to another, amino acids, or the color of an animal's iris. The fewer transformations, the shorter the tree, and therefore the more parsimonious. In this method, what programs do is to investigate as many alternative topologies as possible (or all if their array has less than 25 terminals; see more details below) given their character array. Each will be measured, and the shorter (optimal) trees will be retained as the most parsimonious result.
The answer is B. By polluting near by streams with pesticides and herbicides
