Which of the statements best describes the Theory of Natural Selection?
In nature, the organisms with desirable characteristics may survive, while
those with weaker traits may not.
Which idea best describes the theory of evolution?
Species are related by common descent.
An adaptation promotes..
chance to survive and reproduce
Vertebrate forelimbs are most likely to be studied in?
Comparative anatomy
All of these are true about fossils EXCEPT?
A. They indicate that life has a history.
B. They are pieces of evidence of life in the past.
C. The older the fossils, the less they resemble modern-day species.
D. They look precisely like modern-day species, regardless of their age.
D. They look precisely like modern-day species, regardless of their age.
Which is accurate about the description of homologous structures?
Structure that functions and later on disappear
Natural selection states that…
nature selects the variations within a species that are most useful for
survival.
The criterion used to determine if an organism is a new species is based on
reproduction
Which of the following statements does NOT describe Darwin’s theory of natural
selection?
A. Members of a population will compete.
B. Populations tend to reproduce in small numbers.
C. Members of a population have heritable variations.
D. Some members of a population have adaptive traits.
B. Populations tend to reproduce in small numbers.
Which of the following describes indirect pieces of evidence for evolution?
It is something that does not involve actual observation of evolution but for
which we can infer that change has taken place
The strongest evidence of evolution from a common ancestor is
similar DNA sequences.
What does it mean by direct evidence for evolution?
It consists of observations of actual evolution
Refers to ancient story or set of stories, especially
explaining the early history of a group of people.
MYTH
Held the idea that all forms of life were evolved in
their present form by a divine being, and they
remain unchanged from the beginning
CREATIONISM
Any preserved remains impression or trace of any
once-living thing from a past geological age
Fossils
The doctrine that sudden catastrophes, rather
than continuous change, cause the main features
of the Earth’s crust
CATASTROPHISM
It is a geological theory that describes the
processes shaping the Earth and the Universe. It
states that changes in the Earth’s crust
throughout history have resulted from uniform,
continuous functions that are still occurring
today.
UNIFORMITARIANISM
method used to determine the age of the rocks by comparing them
Relative Dating
Done by analyzing the age of fossils & rocks where the fossils were found
Absolute Dating
Homologous structures?
Similar Structure
DIffering Function
From common ancestor
Analogous Structure?
Differing structure
Similar Function
Not from common ancestor
