Question

In Linnaeus's time, all living things were grouped into two kingdoms. Later, there were five kingdoms, and know we have six kingdoms. What is the main reason for this increase in the number of kingdoms?

Scientists have discovered organisms that were previously unknown, so new kingdoms had to be created for them
Kingdom Plantea had to be split up into several kingdoms when scientists found that not all plants photo synthesize.
As scientists learned more about genetics and biochemistry, some organisms were moved out of existing kingdoms and into new ones.
Since the time of Linnaeus, what is the main reason for this increase in the number of kingdoms?

A.Scientists have discovered organisms that were previously unknown, so new kingdoms had to be created for them
B. Kingdom Plantea had to be split up into several kingdoms when scientists found that not all plants photo synthesize.
C. As scientists learned more about genetics and biochemistry, some organisms were moved out of existing kingdoms and into new ones.
D. Since the time of Linnaeus, many new organisms have evolved, and most of them don't fit into the original kingdoms.

Answer 1

Correct answer: C). As scientists learned more about genetics and biochemistry, some organisms were moved out of existing kingdoms and into new ones.

As the scientist learn and understand more about the genetics and biochemistry they are able to solve the evolutionary puzzles of the life and they know how to classify organism that appears similar to one species but they share common behaviors with the other species.

In 1969 R.H Whittaker give the five kingdoms of classification in his classification three kingdoms were added to previous two kingdoms of classification of plant and animals. These added three kingdoms were Monera, Protista, and Fungi.

Hence, the correct answer would be option C.

Answer 2

"As scientists learned more about genetics and biochemistry, some organisms were moved out of existing kingdoms and into new ones" is the main reason for this increase in the number of kingdoms. The correct option among all the options that are given in the question is the third option or option "C".
