4groups of actually or potentially interbreeding natural populations that are reproductively isolated from other groups: [blank_start]Biological species concept[blank_end]
- ABiological species concept
5[blank_start]Phylogenetic Species Concept[blank_end]: the smallest
diagnosable cluster of individuals within which
there is a parental pattern of ancestry and descent- APhylogenetic Species Concept
6[blank_start]Allopatric Speciation[blank_end]: occurs when the population is divided by a barrier and each population evolves adaptations to different environments. Character development and reinforcement help to solidify reproductive isolation even when the population comes back and contact
- AAllopatric Speciation
7[blank_start]Parapatric Speciation[blank_end]: occurs when a population is separated and each population evolves adaptations to different environments
- AParapatric Speciation
8[blank_start]Phylogeny[blank_end]: evolutionary branch pattern known as the family tree or tree of life.
- APhylogeny
9[blank_start]Evolutionary constraints:[blank_end] Complex adaptations involving many genes become difficult to "undo"
- AEvolutionary constraints
10[blank_start]Sympatric speciation[blank_end]: Selection is strong enough to change populations significantly and overcome large amounts of gene flow.
- ASympatric speciation
11Genetic differences are usually tied to an approximately constant genetic mutation rate. If genes change at a constant rate, and we know the number of differences between 2 species, we can calculate how long ago they diverged. This is known as the [blank_start]molecular clock[blank_end].
- Amolecular clock
12Features primates have that mammals don't:
- AGrasping hands and feet
- BSmall litters
- CLarge brains
- DPostorbital bar
- EConvergent orbits
13Primate diets consist of:
1. [blank_start]Proteins[blank_end]: essential for many aspects of growth
2. [blank_start]Fats, oils, carbs[blank_end]: good sources of energy
3. [blank_start]Vitamine and minerals[blank_end]: help regulate many metabolic functions- AProteins
- BFats, oils, carbs
- CVitamins and minerals
14Past a certain body size, it becomes energetically unfeasible to supplement diet or rely extensively on insects (insectivores) Similarly, below a certain body size, it is energetically unfeasible to rely extensively on leaves (folivore). What is this referred to as?
- ALinnean taxonomy
- BPrimate ecology
- CKay's threshold
15Frugivores, animals that rely on fruit-based diets, mainly have what types of dental adaptations?
- ALarge, broad incisors
- BSmall Incisors
- CPoint Canines
- DLow, rounded molar cusps
- EHigh, sharp cusps
16Folivores, animals that rely on leaf-based diets, mainly have what types of dental adaptations?
- ALow, rounded cusps
- BHigh, sharp cusps
- CSmall incisors
- DStout incisors
17Insectivores, animals that rely on insect-based diets, mainly have what types of dental adaptations?
- AHigh, sharp cusps
- BLow, round cusps
- CSmall incisors
- DSharp canines
18Gumnivores, animals that rely on the gums and saps of trees, mainly have what types of dental adaptations?
- AStout incisors
- BLong incisors
- CSharp cusps
- DLow, rounded molar cusps
19Living in groups is important for primates because they're better able to find and defend resources. It also provides protection from predators.
- AVerdadero
- BFalso
20Name the type of social group
Females maintain separate home ranges with dependent offspring; males may overlap multiple female home ranges.
[blank_start]Solitary[blank_end]- ASolitary
211 male and 1 female live together and share a territory with dependent offspring
[blank_start]Pairs[blank_end]- APairs
22Multiple males and multiple females form a group with dependent offspring and share a home range/territory.
[blank_start]Polygynandry[blank_end]- APolygynandry
23Males mate with multiple females, but females in a group mate with only one (resident or dominant) male.
[blank_start]Polygyny[blank_end]- APolygyny
24One breeding female, mates with one or more partners and others in the group help raise the offspring.
[blank_start]Polyandry[blank_end]- APolyandry
25Main concerns of primate conservationists
- AHabitat destruction
- BHunting
- CPet trade
- DDiseases
26Females are constrained by reproductive biology due to needing to carry the fetus internally as well as breastfeed. Most male mammals are not highly involved in the caretaking of infants. Female’s reproductive success depends on her ability to obtain enough resources to support herself and her offspring.
- AVerdadero
- BFalso
27[blank_start]Sexual selection[blank_end]: Characteristics that increase male success in competition for mates will be selected. A special category of [blank_start]natural selection[blank_end] that favors traits specifically for increased mating success.
- ASexual selection
- Bnatural selection
28[blank_start]Natural selection[blank_end]: favors phenotypes in both males and females that allow them to survive and reproduce.
- ANatural selection
29Selection favoring traits that enhance success in direct male-male competition: [blank_start]Intrasexual selection[blank_end]
- AIntrasexual selection
30Selection favoring making males more attractive to females: [blank_start]Intersexual selection[blank_end]
- AIntersexual selection
