week 4

Question 1

systematics

Answer 1

-branch of biology that studies the diversity of life and its evolutionary relationship.

Question 2

Define taxonomy

Answer 2

science that identifies and clarities of new species

Question 3

where is the node in a phylogenetic trees

Answer 3

each branching point is called a node

Question 4

If something has viaration than it is

Answer 4

heritable

Question 5

beak depth is a heritable trait which means it

Answer 5

, and population make-up change as a result of selection.

Question 6

artifical selection

Answer 6

selection that occurs in human interference

Question 7

Define anagenesis

Answer 7

Gradual evolution of a species that continues to exist as an interbreeding population.

Question 8

cladogenesis

Answer 8

occurs when there is branching or splitting, leading to two or more lineages and resulting in separate species.

Question 9

The 2 types of Rate of speciation

Answer 9

1. Gradualism
   2, Punctuated Equbrium

Question 10

Punctuated Equbrium

Answer 10

Periods of sudden change, which result rapidly evolving species

Question 11

Define the term Hox Changes

Answer 11

Mastered genes, that tell other genes where to put genes.

Question 12

how might mutations have a selective advantage

Answer 12

advangaeous traits

Question 13

Define virulence

Answer 13

pathogen’s or microorganism’s ability to cause damage to a host.

Question 14

why has cause genetic diaster amongst pugs

Answer 14

Pugs and selective breeding forms what pugs look like now.

Question 15

Define Maladaptation and what it can be caused by

Answer 15

Maladaptation can occur from mutation, genetic drift, variation in selection, gene flow, lack off
sufficient genotypes. A trait that causes more harm than good.

Question 16

what are the 3 componets of taxon

Answer 16

Name : what group belong to
2. Rank : where does it fit in phylogeny
3. Content : relevant to species concept

Question 17

Define homoplasticity

Answer 17

superficial similarity due to similar
selective pressures to fill niches. Are traits that development independtly but may look the same

Question 18

what is an example of descent with modification

Answer 18

Birds have different size of beaks that could feed on
different things.

Question 19

Convergent or parallel evolution key difference

Answer 19

different starting points and look the same is convergent/ parallel start
off similar but look different over time due to selective pressure

Question 20

does selection produce evolution at the locus

Answer 20

NO
