__________ is the change in the characteristics of species over several generations and it relies on
the process of natural selection.
Evolution
______________________, was the first biologist to believe that life forms do evolve.
Jean Baptiste de Lamarck
He proposed the inheritance of acquired characteristics,
which is also called as the ___________ _________.
Lamarckian Evolution
________ ______ published his book, On the Origin of Species by Means of Natural Selection.
Charles Darwin
Charles Darwin was only 22 years old when he got a chance to set sail
aboard the _________ to travel around the world and map the coasts of South America.
Beagle
His Beagle voyage allowed him to develop a theory that would contradict the special
creation of every organism and imply that all species evolved from a common ancestor through a process called ________ ______.
natural selection
_______ is a set of genetically acquired traits that makes organisms better suited to their
environment.
Adaptation
________ are examples of evidences that paleontologists use in studying evolution. They are traces of
organisms that lived in the past and were preserved by natural process or catastrophic events.
Fossils
This method is used to determine the age of rocks by comparing them with the rocks present in the other layer. The younger sedimentary rock layer is assumed to be found on top and the older rock is found at the bottom layer
Relative Dating
This type of dating is used to determine the age of rocks using the decay of radioactive isotopes present among the rocks such as Carbon-14. All organisms have decaying Carbon-14 in them.
Radiometric Dating
It is used to tell the age of organic materials. Art collectors use carbon dating to determine if a piece of artwork is genuine or not.
Carbon Dating
Precambrian, Paleozoic,
Mesozoic, and Cenozoic.
Geologic Time Scale
These refer to structures from
different species which have similar internal framework,
position, and embryonic development. Homologous structures may have the same origin or ancestors but different functions. This type of evolution is called divergent evolution. The forelimbs belonging to a dog, man,
cat, bat, bird, lizard, and whale are structurally the same, but
are functionally different.
Homologous structures
The structures of unrelated species may evolve for them to look somewhat the same because the structure has adapted to similar functions. In another words, analogous structures have similar functions but different in origin. In convergent evolution, analogous structures of unrelated organisms from different ancestors developed a similar function. Example: The wings of birds, bats, and insects exhibit the same functions.
Analogous structures
