11
Q

What are the two types of specification

A

Transformation: Through mutations the strongest form is created
Divergence: One or more species is formed through mutations from an orgin and increase biodiversity

16
Q

Homolegus

A

Same strcture, diff function same orgin

17
Q

What needs to happen for specification to occour

A

Geological barriers
Biological barries (cant breed with one another)

18
Q

Selective advantage

A

Mutations that lead to some some sort of advantage

19
Q

Embrylogy

A

Similar embryos in related groups

20
Q

Divergence

A

One or more species is formed through muations and creates several.

21
Q

Mutations

A

When DNA changes when mating

22
Q

What are the two paces of eveolution

A

Gradualism: Gradual change stready and big changes occor by small ones
Puncuated evolution: Rapid change like after an extinction, after equlibrium there is little change after being interupted

23
Q

Biogeography

A

Study of the past and present organizums in diff locations
Geographically close enviroments have close species

24
Q

Embroyology

A

Shows the similarities between embryos

25
Q

Adaptive radiations

A

Diversifation of common ansestial structures into many new ones
(finches of galapgoes)

26
Q

Evidence for evolution

A

The fossils found closer to the surface have a closer relation to living species. Not all older species appear at the same ime

27
Q

Natural selection last points

A

Life forms from an ansestor
All things have a common ansestor
Everything has a common orgin
Species evolve through mutations

28
Q

Analogus

A

Same strcutre diff function diff orgin

29
Q

Physcologlical adaptations

A

Metabolic or physological adaptation to hel an organizum survive

30
Q

Puncutated eqilibrium

A

Periods of rapid chane after an extinction
After equilirium there is little change puncuated by specifcation

31
Q

Aristotle

A

There is a heiarchy that life existed uncahanged in a scala natura

32
Q

Structural adapations

A

Physical feature gained it help it survive

33
Q

Prezygote

A

Mating

34
Q

Transformation

A

One species through mutations creates the best form and out lives the others.

35
Q

Anatomy

A

Homolegus structures have the same structure, diff function, same orgin
Anaolgus have the same purpose, diff structure diff orgin

36
Q

Specification

A

Formation of new species
