: any cellular organism that has no nuclear membrane, no organelles in the
cytoplasm except ribosomes, and has its genetic material in the form of single continuous
strands forming coils or loops, characteristic of all organisms in the kingdom Monera, as
the bacteria and blue-green algae.
: bacteria and archaea.
coral would be an example.
Social behavior in non-insect invertebrates: live in colonies, polyps, social colonies of
Cooperative non-insect invertebrates: Portuguese man of war, lots of polyps living

to find a mate physically. Protects the crabs from predation because of groups.
there is a lower amount of predation, and if a crab goes by itself, there is a higher chance
Invertebrates are animals that don’t have vertebrates.
Includes coral and
jellyfish, crabs, spiders, and snails.
: any organism having as its fundamental structural unit a cell type that
contains specialized organelles in the cytoplasm, a membrane-bound nucleus enclosing
genetic material organized into chromosomes, and an elaborate system of division by
mitosis or meiosis, characteristic of all life forms except bacteria, blue-green algae, and
other primitive microorganisms.
: animals, plants, fungi and protists are all eukaryotes.
warm-blooded, vertebrate animals characterized by the presence of sweat
glands, including those that produce milk, and by the presence of hair, three middle ear
bones used in hearing, and a neocortex region in the brain.
: raccoons, dogs, koalas.

adult stage characterized by three pairs of legs and a body segmented into head, thorax,
and abdomen and usually having two pairs of wings.
: flies, crickets, mosquitoes, beetles, butterflies, and bees.
Give examples for social groups that are composed of a) close kin, b) a mix of related
and unrelated individuals, and c) large groups of unrelated individuals. How prevalent do
you expect cooperation/altruism to be in each of these groups?
Close kin: lions and elephants
A mix of related and unrelated individuals: ants
