Genetically and evolutionarily, which pairing is most closely related?
Modern human and neanderthal
which is the most evolutionarily advanced feature?
bi-lateral symmetry
an overlap of niches leads to
competition
a stable community that develops at the end of a successionary sequence is called
a climax community
which is the proper sequence, from least specific to more specific
primate - anthropoid - hominid
which statement best describes how energy moves through an ecosystem?
energy is dissipated or lost as heat as it makes its way through an ecosystem or food chain
birds are unique because
they are the only animals with feathers
resource competition, disease, and predation are ____ controls on population growth rates
density dependent
what type of animal farms fungus for food
ants
what feature is unique to the mammals
they have hair and/or fur
what is the best biological definition of a population
groups of individuals of a certain species in a given area
what selective pressure helped drive the movement of animals to the land
abundant food; lack of predators
which was the first human ancestor to walk erect
australopithicus afarensis (lucy)
which type of organism is represented by 350,000 named species
beetles
the animal phyla that contains the greatest number of named species is
arthropoda
the most intense competition occurs between
members of the same species
what percentage of the world's population is malnourished
33%
camoflage is a technique used by
both predators and prey
what distinguishes the sponges from the other animals
they do not have true tissue
the first animals to make a complete break from the aqueous environment are the
reptiles
which most accurately describes the place of Neanderthals in the hominid lineage
the Neanderthal lineage was an entirely separate lineage than the human lineage
The type of symbiotic relationship where both participants benefit is called
mutualism
in humans, why is a vegetarian lifestyle energetically less expensive than a meat eating lifestyle
organisms living at higher trophic levels require more energy and resources to produce and maintain
the statement that humans evolved from apes
is not true, because each evolved separately from a common ancestor
what type of organism is a coral
cnidarian
our species arose about how many years ago
150,000 - 200,000
what is one way that the human race has been able to circumvent the limiting factors that restrict population growth in other species
medicine
why was the tiklaakit find in northern Canada of interest to evolutionary biologists
it is a missing link between lobe-finned fish and the partial movement to land by amphibians
which of the following is an arthropod
lobster, insects, spiders, and shrimp (all of the above)
what happens to a population of organisms to limit continued J-shaped growth
they reach their carrying capacity
populations of living things grow
exponentially
Keystone species
one or a few species in a community on which many of the other species in the community are directly or indirectly dependent
Niche
the ntire range of physical and biotic conditions in which individuals of a population live and reproduce
Resource partitioning
the long term evolutionary trend toward resource specializztion among species
coevolution
long term result of close interaction between two species; may involve competitive interactions, predation or mutualism
competitive exclusion
the ecological rule that two species whose niches overlap substantially cannot both persit in the same habitat
which animal lacks organs
cnidarians
which of the following does not cycle through an ecosystem
energy
which is a plausible explanation for the extinction of Neanderthals
lack of sufficient cultural knowledge to allow transmission of survival skills
energy enters an ecosystem by which means
photosynthesis
the most abundant and diverse group of vertebrate animals is the
fishes
what most characterizes a primary producer
photosynthesis
what might be a consequence of removing a keystone species from a community
overall biodiversity could significantly decrease or crash
Why are spiders not insects
they have a single lens eye, not a compound eye
in evolutionary terms, which type of organism is most primitive
jawless fish
the human population of the Earth is now about
almost 7 million
anatomical, cellular and genetic evidence has now estavlished that the ancestors to modern birds were
dinosaurs
one characteristic that distinguishes the cartilaginous fishes from other vertebrates is
they dont have true bone
