f. Production of coacervates and microspheres with
cell-like structures
3. Theory of Evolution through _____________
inheritance of
Lamarck
acquired traits – ____________
long
necks because their
• Giraffes have ________
_______
ancestors had to stretch to reach high leaves
webbed
• Ducks have ___________
feet because their ancestors
stretched their toes
• Traits acquired during an organism’s lifetime were
offspring
passed to their ___________
• This theory has been proved to be wrong!
4. Theory of Evolution through Natural Selection Darwin
__________
time
a. Evidence that species change over _______
fossil evidence
• ______
DNA
• genetic evidence in _________,
amino acid sequence
comparisons
b. Details of Darwin’s theory of natural selection
produced
• More offspring are ___________
than can
survive
_________—there
is a struggle for survival
genetically different
• Offspring are ____________
• Those offspring with traits that give them an
survival
advantage for __________
are more likely to survive
long enough to reproduce and pass on their traits
genes
• Over time, the “advantageous” ________
will become
more common in the gene pool
environment cause changes in
• Changes in the _____________
which genes are selected for or against
Macro-evolution
c. ___________________
is evolution on a large scale over
long time periods and involves the appearance of a new
species
Micro-evolution is evolution on a small scale over a
d. ________________
short time period and shows a change on the frequency of
a gene within a population
Adaptive radiation
e. _____________________
is the most common evolutionary
pattern. It is when two related species become less alike
over time.
Convergent
f. _____________
evolution is when two unrelated species
independently develop a characteristic that appears to be
the same, such as the eye of a human and the eye of an
octopus.
The current system of two-word names was
