Q

Evidence for evolution

A
Comparative anatomy
biogeography
Embryology
Fossil record 
Biological classification 
Molecular biology
2
Q

Species

A

A reproductively isolated population able to interbreed and produce fertile offspring

3
Q

Allopathic speciation

A

Species separated geographically develop into different species

4
Q

Sympatric speciation

A

Populations in the same environment adapt to fill different niches

5
Q

protobionts

A

Droplets of segregated chemicals - early protobionts were RNA that evolved into DNA

6
Q

Analogus structures

A

Similar function different origin

7
Q

Homologous structures

A

Same origin and structure different function

8
Q

Punctuated equilibrium

A

Large change occurs quickly with long periods of no change

9
Q

Molecular clock hypothesis

A

Linear rate of evolutions

10
Q

Stabilizing selection

A

Eliminates extreemesat both ends

11
Q

Directional selection

A

One extreme is selected against

12
Q

Disruptive selection

A

Favors both extremes but not the middle

13
Q

prezygotic barriers

A

Ecological, temporal, behavioral, mechanical physiological

14
Q

Post zygotic barriers

A

Inevitability or sterility of offspring

15
Q

Domains

A

Archaea, bacteria, eukaria

16
Q

Eukaryia

A

Split into four groups: protoctista, fungi, playmate, and Anamalia

17
Q

Radial symmetry

A

Have a side with a mouth and one without, but theres no specific back or front left or right

18
Q

Bilateral symetry

A

Like humans, have head back front bottom etc

19
Q

chordata

A

Animal group that has any of the following features: Notochord, dorsal, hollow nerve chord, pharyngeal slits
INCLUDES: fish, amphibians, reptiles, mammals

20
Q

anagenetic changes

A

Evolutionary changes without speciation

21
Q

arthropods

A

Group of organisms with the MOST diversity - over 1 million types discovered

22
Q

angiosperms

A

Flowering plants

23
Q

gymnosperms

A

Plant group that includes pine
