Evolutionary Relationships Between Organisms Are Determined by

question 37

Multiple Choice

Evolutionary relationships between organisms are determined by

• A) molecular evidence and anatomical homologies.
• B) molecular evidence, anatomical homologies, and fossil records.
• C) molecular evidence, anatomical analogies, and fossil records.
• D) molecular evidence and fossil records.
• E) molecular evidence, anatomical homologies, anatomical analogies, and fossil records. Anatomical analogies are not useful in determining evolutionary relationships because they are the result of convergent evolution. In convergent evolution, distantly related organisms may develop similar adaptations to the same environment, but this does not imply an evolutionary relationship between the two organisms.

Definitions:

Standard Deviation

A statistic that measures the dispersion or variability of a set of data points in relation to their mean, indicating how spread out the data points are.

Mean

The average of a set of numbers, calculated by adding all the numbers in a set together and then dividing by the count of those numbers.

Standard Deviation

A calculation that determines the extent of variability or dispersion in a series of values.

Normal Distribution

Normal distribution, also known as Gaussian distribution, is a continuous probability distribution that is symmetrical around the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.
