these are all key synapomorphies that distinguish primates from their ancestors
large relative brain size, forward facing eyes w/ color vision, opposable digits, short jaws, sociality, etc.
define ecology
the study of how living organisms (biotic) and the physical environment (abiotic) interact
these are the drivers of earth's climate system
what are uneven heating of the earth, atmospheric and oceanic heat redistribution, and the coriolis effect
individuals from populations with this type of density may experience difficulty finding mates
low population density
These are thought to be the common ancestor of primates, specifically Purgatorius
What is an arboreal shrewlike mammal
define population and name two main characteristics of a population
population: a group of individuals of the same species living in an area at the same time. populations are characterized by density, dispersion, survivorship, birth and death rates, age structure, growth rates, and size
Climate components include temperature, wind, sunlight, and this.
what is precipitation
This expression is equal to the rate of change of a population's total size (delta N / delta t)
N(b-d)
This is the main factor distinguishing anthropoidea from other primates
What is brain size?
this type of ecology emphasizes the energy flow and chemical cycling between organisms and the environment
what is ecosystem ecology
While aquatic biomes are characterized by the physical environment, terrestrial biomes are characterized by this
What is predominant vegetation?
You are considering two fossilized primate skeletons. One exhibits evidence of a prehensile tail, a flattened nose with nostrils directed to the side, and is fairly small. The other exhibits no evidence of a tail, is larger, and seems to have had downward directed nostrils. Which of these do you conclude is closer related to hominoids?
the second fossil
Arising from old world monkeys, this lineage includes the extant genera gibbons, orangutans, gorillas, chimpanzees, and humans.
What are hominoids?
this is the formula for instantaneous growth rate of a population
dN/dt = rN
describe the physical mechanisms of atmospheric heat redistribution
solar energy input is greatest at the equator, warm air rises and travels poleward then cools and sinks around 30 degrees from equator, cycle continues at 30 degree intervals
These are inescapable compromises between traits that allow organisms to adapt to a particular set of conditions
What is a fitness trade-off
to earn these points, correctly describe differences between gorilla and human skeletal anatomy (on slide)
.
resource availability and new community interactions (i.e. invasives) can both impact this for a population
what is carrying capacity
to get these points, correctly describe the formation of a rain shadow (in slides)
.
Anthropologist Margaret Mead famously cited an ancient femur that had been broken and healed as the earliest sign of civilization in a culture. Using what we've learned about in BIOL 1120, why might she have argued this?
healing a femur requires the aid and attention of other individuals protecting the injured person (societiality, resource control)
