Question

A scientist has discovered a new, extinct species of mammal. Which of these concepts would be most useful for defining the taxonomy of this species?

Select one:

a. none of these methods would be useful.

b. Phylogenetic species concept

c. All of these methods would be equally useful.

d. Phenetic species concept

e. Biological species concept

Answer 1

Many species concept has been given to define taxonomy of species

Now coming to the question as the scientist has discovered new extinct species which means only fossil is present of that species

Concept use to give Taxonomy of species has been asked

Lets go to each option one by one

Option b Phylogenetic species concept given by concraft

According to which all individual having similar molecular characteristic (DNA sequence) belongs to same species

As the discovered species is fossil we can easily know its DNA sequence hence this concept can be used to give taxonomy of species

Hence option b is correct

Option d Phenetic concept also k/n as morphological species concept according to which species morphologically similar belongs to same species

But as given species is fossil we can not identify it morphologically hence this option d is incorrect

Option E it is incorrect as according to Biological species concept organism which can nterbreed and produce viable fertile offspring belong to same species

As species discovered is fossil how we can check if they can interbreed

Hence option E is false

Other option A &C can be eliminated

Hence the correct answer is option B Phylogenetic species concept
