Ch. 1: Science of Zoology

Question 1

Answer 1

1) Did not explain how changes are passed down

2) Did not explain where the changes came from

Question 2

Microevolution

Answer 2

Variation within species

Question 3

Macroevolution

Answer 3

Variation among species

Question 4

4 main concepts of species (TBEP)

Answer 4

1. Typological
2. Biological
3. Evolutionary
4. Phylogenetic

Question 5

Typological concept of species

Answer 5

Based on morphological similarities

- Assumes that species do not change

Question 6

Biological concept of species

Answer 6

Based on similarity, niche, and the ability to interbreed and produce viable offspring
- Limits asexual species

Question 7

Evolutionary concept of species

Answer 7

Based on biological concept plus evidence of ancestry

- Limits species with little ancestral information

Question 8

Phylogenetic concept of species

Answer 8

Based on the evolutionary concept and in any recognizable genetic variation resulting from isolation

Question 9

How does speciation proceed?

Answer 9

• Mutations
• Spatial/temporal isolation
• Niche specialization and reproductive barriers

Question 10

Adaptive radiation

Answer 10

Formation of various species from a common ancestral form
