W4 Flashcards
According to Dubeck et al., 2004 all living
organisms share characteristics which
Biologically distinguish them from non- living things. The
following are the characteristics:
Cellular respiratory, Growth and development, Reproduction, Ability to response to stimuli and Homeostasis
Two ways to relate time in geology
Relative time and absolute time
(“chronostratic”)
subdivisions of the Earth’s geology
in a specific order based upon
relative age relationships
Relative time
(“chronometric”)
numerical ages in “milions of years’
or some other measurement.
Absolute time
Two types of evidence
Direct Evidence and Indirect Evidence
It can be directly
observed or seen
Direct Evidence
It does not
involve actual observation of evolution
but from which evolution may be
inferred
Indirect Evidence
It is the study of the distribution
of species on Earth in the past
and present, and how the
distribution is affected by abiotic
factors such as habitat and
climate
Biogeography
Three disciplines of biogeography
Historical, ecological, and conservation
is also called
paleobiogeography and studies species distribution now as it
relates to distribution in the past
Historical Biogeography
examines the distribution ot
species in relation to biotic and abiotic factors in the
environment.
Ecological Biogeography
It anticipate future conditions so
that planning can be done to protect the biodiversity
on Earth.
Conservation Biogeography
The father of biogeography
Alfred Russel Wallace
It place important
events and species in the appropriate
geologic era.
Fossil record
A distinct layer of rock that fossils are found in
Strata
It states that in undisturbed
rock sequences the bottom layers are older
than the top layers
Law of superposition
All living cells have the same basic DNA
structure and use the same genetic
code. Proteins produced from genes all
come from the same set of amino acids.
DNA and protein structure
It is defined as similar biological
structures or sequences in different
taxa, thus implies divergent evolution
Homologous structures evolved from
a common ancestor.
Homology
It is the study of the development,
structure, _and function of embryos
Embryology
All living things evolved from a single
common ancestor. There are certain key
molecules and biochemical mechanisms
shared by incredibly different organisms
For example, all organisms use DNA and/or
RNA for their genetic code
Evidence from Physiology and Biochemistry
