EVOLUTIONARY 3

What is a species?

the fundamental unit of evolutionary change

all groups of individuals that send genetic migrants back and forth

a group of interbreeding populations

a group of organisms with an independent evolutionary trajectory

Which of the following transitions in energy allocation do you expect to see before vs after sexual maturity is reached?

Growth, then repair

Evolutionary game theory

can be used to explain the evolution of altruism

can be used to explain how cooperation can evolve in populations

can be used in a “Prisoner’s Dilemma” game show to show that an ESS is always to defect, even though cooperation leads to a higher average payout

can be used to explain why unrelated vampire bats would share a blood meal

In parental studies in villages in Trinidad, Flynn discovered that:

there was less interaction but more of it was agonistic (negative) with non-genetic children

Which of the following is FALSE?

Earlier human species died sequentially, leading to Homo sapiens today

What is currently the earliest known hominin?

Sahelanhropus tchadensis

Which behavior results in a cost to both actor and recipient?

spiteful

If the African Replacement theory was true, allele patterns should demonstrate:

greater diversity in Africa with European and Asian alleles as subsets of African alleles

Which trait would we likely see appear around the same time that language evolved?

larynx lower in throat

Every concept of species and speciation has what common thread?

restricted gene flow

What features of Homo floresiensis make this discovery so interesting?

that this new species of human temporally overlapped with modern humans

given the data that we know now, what can we say about Homo sapiens?

they evolved in Africa

They hybridized with neanderthals and denisovians

they co-occured with multiple species of hominin

Which of the following hypotheses best describes the virulence evolution for the majority of known pathogens?

trade-off hypothesis

Male reed buntings do not always father all nestlings given birth by their mate. Therefore, we would expect that male reed buntings would allocate… resources to clutches where … chicks are fathered by them

fewer, fewer

you are studying two populations of white-tailed deer and notice that the populations are quite distinct in many traits, including body size, size of offspring, and number of offspring. Natural selection should act on the deer in each population in such a way that they allocate energy to maximize….?

lifetime reproductive success

first species of hominin to leave Africa?

Homo erectus

The wealth of evidence of early hominin evolution is that the pattern of evolution leading from our last common ancestor to present day homo sapiens has been a steady transformation of a single lineage.

false

all genetic evidence agrees with the fact that humans are more closely rlated to chimps than either are to gorillas

false

indirect fitness is an important part of inclusive fitness. indirect fitness refers to

reproduction of relatives made possible by an indivicuals actions
