Distinguish between morphological, phylogenetic, and biological species concepts. What are the advantages and disadvantages of each? What notion is common to each of the species definitions that we considered? Why do species definitions matter in conservation biology?

00:01 So here according to the question we are going to understand three different type of species concept and when we talk about these three type of species concept there are the start with the first type the first type is known as the morphological species concept and this morphological species concept helps to describe a particular organism or we can say it helps to describe a particular organism group and where all the organisms which are present in this group are comparatively similar in their appearance but these organisms basically we can say are different from the organism from the other group okay so they are different from the other organisms which are present but they are very similar in terms of their appearance so this is the morphological species concept let's talk about the second concept here which is the phylogenetic species concept so the phylogenetic species concept describes that there is a irreducible organism set and this irreducible organism set which is present is it basically includes all the members from one type of common ancestor it means all the members which are present from this set have a common ancestor so from the from this particular concept it will help us to understand that how a particular set of this organism have evolved from certain set of ancestors then when we talk about the third concept which is the biological species concept this particular concept will help us to understand the basically a particular organism group and how this organism group can basically interbreed between themselves and then produce offsprings which are fertile and healthy so all of these organ all of these concepts the basic notion exists with all of these concept is how to describe a particular organism in terms of different set or we can say how to describe a particular species of organism based on different characteristics so when we talk about their advantages advantages we'll start with the morphological one so when we talk about the advantages of this particular concept it will basically help us to understand organism on the basis of their morphology without carrying any harmful situation or without causing any harm to the organism handling of organism is not needed here only the morphology is needed then when we talk about the second aspect which is the disadvantage so the disadvantage of this particular concept is that this concept has a lot of limitations because it is only associated with the morphology of an organism and because of that we cannot understand the close link of the organism with other organism and we basically we can say that we cannot understand the closing which is associated with the convergent evolution of this particular organism so this is the disadvantage of the organism…

Question

Distinguish between morphological, phylogenetic, and biological species concepts. What are the advantages and disadvantages of each? What notion is common to each of the species definitions that we considered? Why do species definitions matter in conservation biology?
