Study Guide for Changes Over Time Test
S7L3. Students will recognize how biological traits are passed on to successive generations.
a. Explain the role of genes and chromosomes in the process of inheriting a specific
c. Recognize that selective breeding can produce plants or animals with desired traits.
S7L4. Students will examine the dependence of organisms on one another and their environments.
c. Recognize that changes in environmental conditions can affect the survival of both individuals and the entire species.
S7L5. Students will examine the evolution of living organisms through inherited characteristics that promote survival of organisms and
the survival of successive generations of their offspring.
a. Explain that physical characteristics of organisms have changed over successive generations (e.g. Darwin’s finches and
peppered moths of Manchester).
b. Describe ways in which species on earth have evolved due to natural selection.
c. Trace evidence that the fossil record found in sedimentary rock provides evidence for the long history of changing life forms.
