Difference between Speciation and Species

Speciation vs. Species

Speciation is the evolutionary process by which populations evolve to become distinct species. In biology, a species is the basic unit of classification and a taxonomic rank, as well as a unit of biodiversity, but it has proven difficult to find a satisfactory definition.

Alfred Russel Wallace

Alfred Russel Wallace (8 January 18237 November 1913) was an English naturalist, explorer, geographer, anthropologist, and biologist.

Alloenzyme

Alloenzymes (or also called allozymes) are variant forms of an enzyme which differs structurally but not functionally from other allozymes coded for by different alleles at the same locus.

Allopatric speciation

Allopatric speciation (from the ancient Greek allos, meaning "other", and patris, meaning "fatherland"), also referred to as geographic speciation, vicariant speciation, or its earlier name, the dumbbell model, is a mode of speciation that occurs when biological populations of the same species become isolated from each other to an extent that prevents or interferes with genetic interchange.

Anagenesis

Anagenesis is an evolutionary pattern defined by a gradual change that occurs in a species without the need for splitting.

Apomixis

In botany, apomixis was defined by Hans Winkler as replacement of the normal sexual reproduction by asexual reproduction, without fertilization.

Asexual reproduction

Asexual reproduction is a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes, and almost never changes the number of chromosomes.

Bateson–Dobzhansky–Muller model

The Bateson-Dobzhansky-Muller Model, also known as Dobzhansky-Muller Model, is a model of the evolution of genetic incompatibility, important in understanding the evolution of reproductive isolation during speciation and the role of natural selection in bringing it about.

Chromosome

A chromosome (from Ancient Greek: χρωμόσωμα, chromosoma, chroma means colour, soma means body) is a DNA molecule with part or all of the genetic material (genome) of an organism.

Chronospecies

A chronospecies is a species derived from a sequential development pattern which involves continual and uniform changes from an extinct ancestral form on an evolutionary scale.

Drosophila

Drosophila is a genus of flies, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or (less frequently) pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit.

Extinction

In biology, extinction is the termination of an organism or of a group of organisms (taxon), normally a species.

Extinction event

An extinction event (also known as a mass extinction or biotic crisis) is a widespread and rapid decrease in the biodiversity on Earth.

Gene flow

In population genetics, gene flow (also known as gene migration or allele flow) is the transfer of genetic variation from one population to another.

Genetic drift

Genetic drift (also known as allelic drift or the Sewall Wright effect) is the change in the frequency of an existing gene variant (allele) in a population due to random sampling of organisms.

Hybrid (biology)

In biology, a hybrid, or crossbreed, is the result of combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction.

Mutation

In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements.

Natural selection

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype.

Neutral theory of molecular evolution

The neutral theory of molecular evolution holds that at the molecular level most evolutionary changes and most of the variation within and between species is not caused by natural selection but by genetic drift of mutant alleles that are neutral.

On the Origin of Species

On the Origin of Species (or more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life),The book's full original title was On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life.

Ring species

In biology, a ring species is a connected series of neighbouring populations, each of which can interbreed with closely sited related populations, but for which there exist at least two "end" populations in the series, which are too distantly related to interbreed, though there is a potential gene flow between each "linked" population.
