Q

Insights

A
  1. species are adaptive over time
  2. forces of nature can be favorable or not
  3. variations are inherited
  4. environments are not static
  5. phylogenetic concept began to emerge
35
Q

a species is a “tip” on a phylogeny, that is, the smallest set of organisms that share an ancestor and can be distinguished from other such sets.

A

Phylogenetic species concept

36
Q

published “Biological Species Concept”

A

Theodosius Dobzhansky

37
Q

How can you say that a group of organisms are one species (Biological Species Concept)

A

they interbreed with each other

38
Q

  • improvement of taxonomic concept
  • rise of Biosystematics
A

Biosystematic Phase

39
Q

study of the diversification of organisms, both past and present, and the relationships among those organisms through time

A

biosystematics

40
Q

attempt to classify and identify organisms (originally plants) according to confirmable differences and similarities in their biochemical compositions

A

Chemotaxonomy

41
Q
  • collection of data, analysis & synthesis
  • introduced quantitative taxonomy (numerical taxonomy)
A

encyclopaedic or holotaxonomic phase

42
Q

divided Plant Kingdom into two divisions: Cryptogamia (non-flowering plants) and Phanerogamia (flowering plants).

A

Bentham and Hooker

43
Q

classifies flowering plants into Magnolids (four orders), Monocots (seven orders), Commelinids (five orders), and Eudicots (36 orders), plus a few taxa of uncertain affinity.
