-
Darwin
noticed that many organisms seemed well suited to
- . surviving in the environments in which they
- lived
-
Based on the adaptations
Charles Darwin observed in finches and tortoises in the Galápagos, he wondered
- if
- finches and tortoises had originated from the same ancestral species.
-
Which of the following ideas
is supported by Darwin’s observation of local variation among tortoises in the
Galápagos Islands?
adaptation
-
In the 1800s, Charles Lyell
emphasized that
- past geological events must
- be explained in terms of processes observable today.
-
Lamarck’s ideas about evolution include the concept that
differences among the traits of organisms arise as a result of
- . the actions of
- organisms as they use or fail to use body structures.
-
The economist Thomas
Malthus suggested that
- without certain checks on
- population size, there would soon be insufficient food for the growing human
- population.
-
When a dairy farmer chooses
to breed the cows that give the most milk in the herd, the farmers are
following the principle of
-
Each
of the following is a condition necessary for natural selection to occur EXCEPT
- there is
- heritable variation among members of the population.
-
Which
statement about the members of a population that live long enough to reproduce
is consistent with the theory of evolution by natural selection?
- They are the ones that are
- best adapted to survive in their environment.
-
The principle of common
descent helps explain why
- birds and
- reptiles share a number of inherited characteristics.
-
Darwin’s concept of natural
selection was NOT influenced by
the work of Gregor Mendel
-
Charles Darwin viewed the
fossil record as
- useful support for his
- theory
-
Modern sea star larvae
resemble some primitive vertebrate larvae. This similarity may suggest that
primitive vertebrates
evolved before sea stars
-
Molecular evidence in
support of natural selection includes
- the nearly universal
- genetic code.
-
. Which characteristic of
Galápagos finches helped the Grants show the results of natural selection?
. the size and shape of their beaks
-
. On the Galápagos Islands, Charles Darwin observed
species similar to mainland South American species.
-
James Hutton’s and Charles Lyell’s work suggests
that
- . Earth is several
- million years old
-
In an
experiment, suppose that the wings of fruit flies were clipped short for fifty
generations. The fifty-first generation emerged with normal-length wings. This
observation would tend to disprove the idea that evolution is based on
inheritance of acquired characteristics.
-
The economist Thomas Malthus suggested that
- without certain checks on population size, there
- would soon be insufficient food for the growing human population
-
According to Darwin’s theory of natural selection,
individuals who survive are the ones best adapted for their environment. Their
survival is due to the
- . possession of
- inherited adaptations that maximize fitness
-
Charles Darwin called the ability of an organism
to survive and reproduce in its specific environment
fitness
-
Charles Darwin’s theory of evolution by natural
selection explains each of the following EXCEPT how
. traits are passed from parent to off spring.
-
Biogeography is the study of
where species and their ancestors live.
-
The number and
location of bones of many fossil vertebrates are similar to those in living
vertebrates. This is evidence in support of which of the following concepts?
common descent
-
.
In humans, the pelvis and femur, or thigh bone, are involved in walking. In
whales, the pelvis and femur shown in Figure 16–1 are
. vestigial structures
-
What principle does
the Grants’ investigation of finch adaptation in the Galápagos
Islands best support?
natural selection
-
The species of finches that Charles Darwin found
on different Galápagos Islands varied in
certain adaptations. One of the most significant was
shape of beaks.
