Evolutionary biology

Inbiology,evolution is change in theheritablecharacteristics ofbiological organisms over generations due tonatural selection,mutation,gene flow, andgenetic drift. Also known asdescent with modification. Over time these evolutionary processes lead to formation of new species (speciation), changes within lineages (anagenesis), and loss of species (extinction). "Evolution" is also another name forevolutionary biology, the subfield ofbiology concerned with studyingevolutionary processes that produced thediversity of life on Earth.

Basic concepts of phylogenetics

[edit]
  • Phylogenetic tree – Branching diagram of evolutionary relationships between organisms
  • Phylogenetic network – Graph used to visualize evolutionary relationships, including reticulation events
  • Long branch attraction – Systematic error in phylogenetics
  • Clade – Group of a common ancestor and all descendants
  • Grade – Non-monophyletic grouping of organisms united by morphological or physiological characteristics
  • Ghost lineage – Phylogenetic lineage that is inferred to exist but has no fossil record

Group Traits

[edit]
  • Symplesiomorphy – An ancestral character or trait state shared by two or more taxa
  • Apomorphy – Two concepts on heritable traitsPages displaying short descriptions of redirect targets
  • Synapomorphy – Two concepts on heritable traitsPages displaying short descriptions of redirect targets
  • Autapomorphy – Distinctive feature, known as a derived trait, that is unique to a given taxon
