Formation of Species

46.7K
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.

The Evidence for Evolution02:55

The Evidence for Evolution

49.9K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

What is Evolutionary History?

44.6K
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

Genetics of Speciation

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

Non-vascular Seedless Plants

The diverse plant life on Earth—consisting of nearly 400,000 species—can be divided into three broad categories based on biological characteristics: nonvascular, seedless vascular, and seed plants.

Area of Science:

  • Evolutionary biology
  • Plant systematics
  • Phylogenetics

Background:

  • Ecological opportunity drives species diversification rates and taxon richness.
  • Asteraceae, the largest eudicot family, vastly outnumbers its sister family, Calyceraceae.
  • Understanding Asteraceae's evolutionary success requires examining diversification dynamics.

Purpose of the Study:

  • Investigate diversification rate dynamics within the Asteraceae family.
  • Identify factors contributing to Asteraceae's evolutionary success and rate changes.
  • Re-evaluate previous hypotheses on diversification drivers like dispersal and polyploidization.

Main Methods:

  • Phylogenetic analysis of Asteraceae and related families (Calyceraceae, Goodeniaceae).
  • Molecular clock dating using relaxed clock methods and updated calibrations.
  • Comparative analysis of diversification rates across major clades and geological time periods.

Main Results:

  • Basal Asteraceae lineages in South America show similar diversification rates to sister families.
  • Diversification rates gradually increased from the Late Cretaceous through the Early Eocene Climatic Optimum.
  • Significant rate shifts were not strongly correlated with intercontinental dispersals or polyploidization, contrary to prior studies.
  • Specific clades (Vernonioid, PF Clade) exhibit transformed diversification rates.
  • African subfamilies underwent rapid divergence during the Middle Eocene.

Conclusions:

  • Asteraceae's diversification is a gradual process, not solely driven by major innovations or events like dispersal/polyploidization.
  • Updated phylogenetic methods and sampling reveal a more nuanced history of diversification.
  • Specific clades and geographic regions show distinct patterns of accelerated evolution.
