b. all traits are adaptions
c. evolution is not just a theory
d. evolution explains the origins of life
C. Evolution is not just a theory
*#10 Evolution is just a theory*
T or F: Mechanisms of Evolution are natural selection, sexual selection and genetic drift
TRUE!!!!!
Which is Which? Natural vs. Artificial
1. Change in genotype frequencies over time due to selective breeding by humans
2. Change in genotype frequencies over time due to differences in reproductive output among individuals
1. Artificial
2. Natural
Similarity in characteristics that result from common ancestry
homology
what is an edge?
branch
What are 3 examples of theories
Gravity, Relativity, Evolution
Origin of Species:
Who wrote it?
When was it written?
What was it all about?
Why did he write it?
Charles Darwin, 1859, Evolution happened by natural selection in the Galapagos, to convince the world evolution occurred and propose a mechanism for how it works
T or F? Humans, birds, and bats had a common ancestor.
TRUEEEEE
copy of genes that are no longer functional
pseudogenes
what are nodes?
most common ancestor of a branch species
Difference between Science and Religion
Science- conceptual framework of observations
Religion- infuse experience with meaning
1. overproduction
2. organisms vary in a pop
3. variation is inherited
Bare bones mechanics of natural selection
Speed of evolution depends on...
the amount of variation and inheritance
sporadic expression/recapitulation of a lost ancestral trait
Atavism
2 branches on a tree
bifurcated tree
Organisms simply evolve what they need
utilized march of progress and simple to complex misconception
Darwins theory in regards to progress
superficially similar but with separate evolutionary origins
Analogous trait
ancestor and some but not all its descendants
Paraphyletic group
how do you read the tree?
bottom to top- use the cut test
Evolution is a march of progress
Misconception #7
Mechanics of natural selection- what does variation mean?
Organisms vary with population
What is Convergent evolution?
independent evolution of similar traits in different lineages
derived character state in a single taxon
autapomorphy
what is a root?
node that represents the most recent common ancestor
