Question

Three reasons why dichotomous keys would be subject to changes over time

Answer 1

A dichotomous key is a rather large sequence of yes/no questions that result in identification of a living thing. This is important because of the level of separation it provides. A dichotomous key is a key that is used to classify a organism. It is like a list of criteria. Each criteria leads to another which will eventually narrow the number of possible species until you arrive at a specific one. A dichotomous key is used to categorize plants and animals. They are used when classifying a newly-discovered species. Categorizing new species is sometimes called 'keying out' the species.

Answer 2

The dichotomous key refers to a tool that determines the unfamiliar organism by comparing its features with the arranged set of mutually exclusive features of distinct species. The dichotomous keys modify with time due to the following reasons:

1. The keys are framed on the basis of the features of the previously known organisms. If one finds novel features in the newly invented organisms, the keys get modify.

2. The organisms can modify their features because of evolution.

3. The dichotomous keys are totally dependent upon history. The scientists may not witness the present evolutionary variations taking place. This signifies that this characteristic will be determined later in the coming time, therefore, the keys modify.
