What is the biological species concept of Ernest Mayr?
Mayr's definition of a species is based on the genetic isolation of populations.A ... difficulty which confronts us in our attempt at a species definition is thatthere is, in nature, a great diversity of different kinds of species. Even if we donot consider such aberrant phenomena as the apomictic species in plants andthe strains of bacteria, there is, even among animals, a great variety of differenttaxonomic situations which are generally classified as species. The question as towhether the species of birds, of corals, or protozoa, and of intestinal worms arethe same kind of evolutionary phenomena is entirely justified. . . It may not be exaggeration if I say that there are probably as many species concepts as there arethinking systematists and students of speciation. [(Mayr 1942: 114-115)]A species consists of a group of population which replace each othergeographically or ecologically and of which the neighboring ones intergradeor interbreed wherever they are in contact or which are potentially capable ofdoing so (with one or more of the populations) in those cases where contact isprevented by geographical or ecological barriers.Or shorter: Species are groups of actually or potentially interbreedingnatural populations, which are reproductively isolated from other such groups.[Systematics and the Origin of Species, 1942: 120]
Hormone and receptor interactions are based on?
The target cell, the receptor, and the species.
The grouping of viruses is based partly on the?
The grouping of viruses is based on the particular species. Viruses are also living organisms which are divided into specific genus and species.
Did Charles Darwin know about the universality of the genetic code when he proposed the methods of evolution?
The modern concept of genetics was unknown during Darwin's lifetime, and for many years after. Darwin based his theory of evolution upon observation of the similarities and differences between closely related species, and how they could have developed.
What is the difference between kingdom and phylogeny?
Kingdom was traditionally the highest level of classification for organisms until recently, when the concept of domains was introduced. There are five kingdoms: Animalia, Plantae, Protista, Fungi and Monera.A phylogeny is the evolutionary history of a species or group of species. They separate organisms by evolutionary relationships (clades), based on comparative cytology and the comparison of DNA, morphological characters, and shared ancestral and derived characters.
What are the differences between the morphological species concept biological species concept and phylogenetic species concept?
The morphological species concept differentiates species by their physical traits, basically. The biological species concept defines a species as generally organisms that breed with others of the same species; rather a genetic isolation concept. The phylogenetic concept is based on evolutionary relationships and is the concept used by cladists.

How are living things classified according to species?
AnswersThere are multiple answers to the question of what is a species. One of the lessons of evolution is that the idea of species is transient. No population of organisms can be said to truly be the same species as it's ancestors. It's important to note that the idea of a species is a human concept. Nature doesn't play that nice. One of the more common definitions and easiest to explain is the biological definition. This basically states that a species is "a reproductive community of populations (reproductively isolated from others) that occupies a specific niche in nature." In other words, a group that can breed with each other. (This definition has obvious failings with asexual organisms.)Some of the challenges to species definitions come from organisms that form "ring species" which, even if forming an incomplete ring, still challenge how we think of a species.Other definitions define a species based on various similarities, either in form, behaviour, or biochemistry.
