Of the following anatomical structures, which are homologous to the wing of a bat?
the tail of a kangaroo
the flipper of a whale
the wing of a butterfly
the arm of a human
Images of the embryo and adult stages of three different organisms are shown.
Which of the following is the best conclusion that can be drawn from this evidence?
Having similar embryos indicates that these organisms eat the same types of food.
Having similar embryos indicates that these organisms live in a similar environment.
Having similar embryos indicates that these organisms share a recent common ancestor.
Having similar embryos indicates that a certain protein controls how many legs the adult organisms will have.
Whales have pelvic (hip) bones, even though they don't have legs. These are called vestigial structures - bones or other structures that aren't useful but are still there. What do whales' pelvic bones suggest?
That whales are related to sharks
That one whale was born without legs and now no whales have legs
That whales have an ancestor that had legs
That pelvic bones have no purpose in any animal
What can be used as evidence for evolution? (select all that apply).
Any common function of structures between species (i.e. birds and insects both have wings)
Body parts of different species that are similar in structure and location.
Similarities of embryos from different species.
Fossil records showing structures and locations of species.
Structures in modern species that are unused and unnecessary, but were used by past species.

Ostriches have wings, but do not fly. Humans have an appendix with no apparent function. Whales contain bones for rear legs. Each of these are examples of...
homologous structures
vestigial structures
analogous structures
natural selection
Researchers discovered that the legs of birds are homologous to the feet of reptiles. Which claim is BEST supported by this fact?
Birds do not require legs
Birds and reptiles have a common ancestor
They randomly developed the same structures
Selection pressures have acted on birds, but not on reptiles
'Homologous structures' refers to:
body parts of two different species that have similar structure and location in each species.
body parts that have the same function, but very different structures.
structures that sound the same.
two organisms that have about the same sized parts of their structure.
What type of evidence of evolution is pictured?
vestigial structures
homologous structures
embryology
DNA studies
Evolved from the same ancestor, but have different functions
