What is Evolutionary History?

40.7K
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.

Evolutionary Relationships through Genome Comparisons

6.4K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Genetics of Speciation

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

The Evidence for Evolution02:55

The Evidence for Evolution

44.9K
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.

Synteny and Evolution02:31

Synteny and Evolution

3.4K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral...

Convergent Evolution01:54

Convergent Evolution

29.5K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

Area of Science:

  • Historical Biogeography
  • Phylogenetics
  • Computational Biology

Background:

  • Reconstructing historical relationships of areas of endemism from taxon distribution and cladistic data presents challenges.
  • Existing methods may not fully account for widespread taxa or missing data.

Purpose of the Study:

  • To present a novel method for reconstructing area relationships using parsimony and compatibility.
  • To develop a data matrix integrating distributional and cladistic information for biogeographical analysis.
  • To address limitations in historical biogeography by incorporating assumptions for widespread taxa and missing areas.

Main Methods:

  • Components are extracted from a data matrix using partial monothetic sets.
  • A derived data matrix is created via boolean multiplication of distributional and cladistic matrices (using additive binary coding).
  • Area-cladograms are generated by identifying mutually compatible components and evaluated based on vicariance and ad hoc explanations.

Main Results:

  • The derived data matrix effectively represents phyletic data and can be modified for specific assumptions.
  • Area-cladograms are constructed by finding maximal sets of compatible components.
  • Evaluation of area-cladograms balances support (vicariance) against contradiction (dispersal, extinction).

Conclusions:

  • The proposed method provides a robust framework for reconstructing historical biogeography.
  • Selected area-cladograms represent the most parsimonious and best-supported historical relationships among areas of endemism.
  • The approach is validated with examples including poeciliid fish genera.
