You are not expected to get all of these right first go round, though many questions here rely on previous knowledge.
This is a mixture of lyrics prediction and assessment of your understanding of terms, and interpretation practice of a passage, to introduce a new topic. We will watch the video after, then receive a new copy of the lyrics to try again with the key turned on.
See...
One cell divide and decide on a thousand fates
Did you ever figure how they know?
The process of cell division as shown in this lyric is...
Choose an appropriate term for this blank in the lyric. Don't stress about whether it's perfect or not.
Did you ever figure how they know?
We
Are built of modules combined in a planned-out way
Each new
Oh
Now there's a science helping us to understand
How our cells encode this architectural plan
Signalling each other with genetic tools oh
Oh yeah
Wow
This process must happen in...

Evo-Devo
Looking at the logic in the ways that we grow
Every directed by a signal key code
that can activate, enhance or veto*
Evo-Devo
In this verse, the term veto could be replaced without losing meaning...
Signals are controlled by other that signal
Calculating in a network labyrinthal
Where the heart and liver and the hands and feet go
Signal mapping tells each region what it ought to be yo
With circuits so deeply built upon
They're than the Paleo
The Paleozoic Era baby
In ___________ pathway
Changes tend to get torpedoed
Where they go calamity goes
As this cyclopic sheep knows...
The word changes in the above verse refers to
See down they cascade like a
Like you and I drosophila
The path that makes us optical
Was laid a long long time ago
Set up set up
In a
On segments embryonic
Split forebrains and asymmetric parts depend upon it
Flipping on genetic switches and logic
From devo to evo
Adult and embryo
Mostly don't evolve in the genes of the (whole)
Safer the mutation aimed at regulation
Keep the building blocks and swap their activation
The word that could best replace building blocks in the above verse is...
Signals trigger patterns of complexity so
Switching up the switches of a signalling node
Gives a modular and simple way to evolve
Relate the terms, connecting thoughts from this verse.

|---|---|---|
evolution | arrow_right_alt | butterflies hatch with different genotypes |
mutation | arrow_right_alt | acts on the phenotype; brown butterfly survives and reproduces in brown land |
coding sequence | arrow_right_alt | the frequency of the brown phenotype becomes more common over generations |
natural selection | arrow_right_alt | controls expression, ex. size, amount, and location of melanated spots on a butterfly's wing |
regulatory sequence | arrow_right_alt | is expressed (is transcribed to RNA and translated to protein), ex. melanin to make spots on a butterfly's wing |
Look at how our spinal segments generate a neat row
Built on a molecular clock
One cycle, one vertebra
One vertebra one vertebra baby
its rate is snakes' developmental cheat code
That and where a lizard's feet grow
They turn off distal aminos
The best synonym for the underlined text is .
They in the above verse refers to the
Evo-Devo
This is how we go from single cells to people
Every generation and in life primeval
Life in variations endless and beautiful
Badaboom!

Patterns are resolved as the signals proceed yo
Map out a gene with a glow tag
Kill it with a morpholino
Short oligo morpholino baby

Voyage of the Beagle
Body plans evolve when proteins steer the genome
In this manner life's beauty grows
Aesthetica in vivo
Evo-Devo
If you're asked about morpholinos on the test, they'll give you extra information. What a morpholine usually does is block of mRNA into protein.
If you're ever asked about morpholinos (unlikely, though similar concepts might show up), you won't need to know about them; they'll describe the morpholino as done above. You do need to know, though, that...
According to the lyrics, what does "Evo-Devo" primarily focus on?
What does the song imply about the relationship between evolution and development?
Which statement describes a common theme in the song?
Which are true messages supported by the lyrics?

One cell divide and decide on a thousand fates
Did you ever figure how they know?
The concept of 'deciding on a thousand fates' is best described by the process of
Back before we blew up the Cambrian like a bomb bomb
Now my eye protein can make you see out of your bom bom
And Hedgehog and its relatives like Indian and Sonic
Identify the monomer and function of the underlined term.
From devo to evo
Parts have alter egos
Homologs evolved from repeats in the schema
Switch a couple bases in the proper places
You'll be watching flies grow legs out of their faces oh yeah
Select the appropriate polymer and function associated with the underlined term.
