What is a Species?

Overview
Genetics of Speciation02:16

Genetics of Speciation

Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.
Formation of Species01:31

Formation of Species

Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.
Phylogenetic Species Concept in Microbiology01:22

Phylogenetic Species Concept in Microbiology

The phylogenetic species concept (PSC) is a framework used to delineate species based on evolutionary relationships, emphasizing shared ancestry and diagnosable genetic traits. Unlike morphological or biological species concepts, the PSC is particularly advantageous for microbial taxonomy, where traditional reproductive or phenotypic criteria often fall short due to the prevalence of asexual reproduction, minimal morphological differentiation, and widespread horizontal gene transfer among...

Conservation of Small Populations02:04

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less likely to...

Summary

The species problem, a long-standing debate in biology, has been largely resolved. This research argues that outdated factors perpetuate the misconception of an ongoing species problem, urging its historical classification.

Area of Science:

  • Evolutionary Biology
  • Philosophy of Science
  • Taxonomy

Background:

  • The concept of species has been debated since Darwin's theory of evolution.
  • A historical 'species problem' arose from the rejection of essentialist species concepts.
  • This conceptual challenge became culturally entrenched in scientific discourse.

Observation:

  • Despite being largely solved decades ago, the species problem persists.
  • Several factors contribute to its perceived intractability.
  • These factors have been identified and refuted but remain influential due to lack of widespread awareness.

Findings:

  • The 'species problem' is a historically contingent issue, not an ongoing scientific impasse.
  • The persistence of the species problem is due to the continued influence of debunked arguments.

  • Scientific understanding has advanced, rendering the traditional species problem obsolete.

    • Implications:

    • Reclassifying the species problem historically will clarify conceptual understanding in biology.
    • Recognizing the resolution of the species problem can refocus research efforts.
    • This shift encourages a more accurate understanding of evolutionary processes and biodiversity.
