GRADED A+
A population of deer was threatened with overpopulation until cheetahs were imported.
After a couple of years, there were fewer deer, but the average running speed of the deer
had increased. This is an example of:
natural selection
The long neck of a giraffe has developed over a long period of time because giraffes have
needed to stretch their necks to reach food high in trees, and that quality has been passed on
through the generations. This view of evolution would correspond with the ideas of
Jean-Baptiste de Lamarck
A population is
all the members of a species that live in a defined geographic region at the same time
What is the difference between microevolution and macroevolution?
Microevolution describes changes within a population over a short period of time, whereas
macroevolution describes larger changes such as the formation of new species over longer
periods of time
Imagine a population of monkeys in South America whose habitat has been reduced to the
point where only 25 monkeys survive.
This is an example of population bottleneck
, Shrews have been documented to travel across frozen lakes and establish populations on
previously uninhabited islands thus, the shrews have a limited gene pool. If this limited gene
pool has allele frequencies that are very different from the allele frequencies found in the
original population, then this would be an example of
founder effect
The biological species concept cannot be applied to bacteria because
they do not reproduce sexually
A population of mountain-dwelling salamanders migrates and splits into two populations
separated by a valley they can not cross. The speciation process that may occur is
allopatric
Animals in the same genus are probably most closely related
evolutionarily
Modern birds are probably direct descendants of
dinosaurs
The sequence of the scientific method is
observation, hypothesis, experiment , and conclusion
Eating a meal is an example of
how living things assimilate energy.
