1801 and again in 1809
7
Q
name five things Lamarck got right
A
- coined the terms vertebrate and invertebrate 2. popularized the term biology 3. understood that species could lose organs if they dont use them 4. proposed the idea that the acquisition or loss of a trait could be preserved by reproduction 5. environment affects the shape and organization of animals
8
Q
name two thing Lamarck got wrong
A
- Organisms can change at will 2. Cut off 22 mice tails thinking they would reporduce a mouse without a tail
9
Q
what is the name of the concept attributed to Lamarck?
A
Inheritance to acquired characteristics
10
Q
what three early observations added to our understanding of evolution, and what do they suggest
A
- hands look similar across species 2. under microscopes, embryonic mammals, birds, and frogs have similar gill slits 3. some species possess traits that seem to have a purpose
11
Q
Evolutionist
A
one who believed that organic structure changed over time
12
Q
the religions of the 1800s and 1900s had one particular tenet that impeded our understanding and acceptance of evolution by natural selection. describe that tenet.
A
god created all species, and they are unchanging.
13
Q
name four central ideas floating around europe as Wallace and Darwin were honing their idea of evolution by natural selection
A
- fossils show great geological time 2.more organisms are born than can possibly survive 3. the enviornment affects shape and organization of animals 4.god made everything as we see it/ god made unchanging species. everything is perfect for its enviornment.
14
Q
Darwin and Wallace noted two things on their trips. what were they?
A
- Species dont look like something that were independently created. 2. Species look like they came from similar species.
15
Q
Wallace and Darwin spent decades trying to answer two questions. What were they?
A
- why do organisms change over time? 2. how does one explain the apparant purpose of traits like shells, beaks, and quills… or hooves?

Q
What is the name of the concept attributed to Darwin and Wallace?

Evolution by natural selection
17
Q
how is Lamarck’s idea similar to that offered by Wallace and Darwin?

Q
how is Lamarck’s idea different from Wallace and Darwin’s ideas?

Q
name and define three ingredients needed for evolution by natural selection
A
variation, inheritance, and selection
21
Q
variation

something you receive from your parents

Q
selection

Q
describe how variation, inheritance, and selection work when evolution by natural selection works
A
variation: raw materials inheritance: only works if there is variation selection: if a trait causes differential reproductive success
25
is sexual selection a kind of natural selection?
yes
26
why did Darwin hate peacocks?
he feels their feathers make it easier for predators to hunt them
27
Sexual Selection
selection for traits that help organisms reproduce rather than survive
28
two kinds of sexual selection
intersexual selection and intrasexual selection
29
intersexual selection
if the trait exists because a female chooses it
30
intrasexual selection

32
in what year did Gregor Mendel publish?

33
what three things did Mendel add to the conversation about natural selection?
-the qualities of parents are not blended -traits are passed in tact with offspring in packets called genes -we get half our genes from mom and half from dad
34

35
When did ethology become a subject?
1950s
36
ethology
animal behavior
37
who was the founder of ethology?
Konrad Lorenz and Niko Tinbergen
38
Tinbergens four whys
1. what is the immediate influence on the behavior? 2.what are the developmental influences on the behavior? 3.what is the function of the behavior? 4. what is the evolutionary origin of the behavior?
39
in what year did George Williams publish his book and what was it called?
Adaptation and Natural Selection (1967)
40
What three things did Williams accomplish?
1. Translated Hamilton's math into something other scientists could understand 2. Provided a standard for when scientists should invoke the concept of adaption 3. squashed the prevalent idea of group selection
41
what is the first common misunderstanding about evolutionary theory? why is it wrong
behavior is genetically determined. this is wrong because awareness of the cause of a behavior allows us to modify it
42
what is the second misunderstanding about evolutionary theory?
if it is evolutionary, we can't change it
43
what is the third misunderstanding of evolutionary theory?
current mechanisms are optimally designed
44
does evolution = natural selection?

45
does natural selection = evolution?
yes
46
three ways to generate evolutionary change
