Honors Biology – Evolution Test with Questionsand correct Answers
Analogous Structure - ✔✔Body structures that have similar functions but
different internal structure and development. Developed through adaptations to
similar environments, not a common ancestor.
Structurally different, yet it functions alike.
Similarities of Embryology - ✔✔Pg. 291
Evidence of evolution through the animals looking similar in early stages of life
(embryo).
Tell us how closely related organisms are.
Vestigial Structure - ✔✔Remnant of a structure that may have had an
important function in a species' ancestors, but has no clear function in the
modern species.
What makes organisms change? - ✔✔The constant change of surroundings /
environment.
What are the three forms of evolution? - ✔✔1. Coevolution
2. Convergent Evolution
3. Divergent Evolution
, Coevolution - ✔✔Evolutionary change in which adaptations in one species act
as a selective force on a second species, inducing adaptations that in turn act as a
selective force on the first species; mutual influence on the evolution of two
different interacting species.
Process by which two species evolve in response to changes in each other.
Convergent Evolution - ✔✔Process by which species evolve in different places
or different times yet develop similar external forms and structures (a result of
adaptation to similar environments).
Process by which unrelated organisms independently evolve similarities when
adapting to similar environments
Divergent Evolution - ✔✔A form of evolution in which the same organism is
placed into different environments with different selection pressures. This causes
organisms to evolve differently, to diverge from their common ancestor. The
resulting (new) species may share structural (but not necessarily functional)
Similarity; divergent evolution produces homologous structures.
When one species diverges into two or more species, becoming increasingly
different over time in response to different environments.
