Imagine going for a walk in
Yellowstone National Park. As you are
observing your surroundings, you
notice something interesting in the
rocks.
Read Part 1. Jot down notes
and drawings that will help
you remember the meanings
of these words. You can use
the sketch/scribble button on
the toolbar.
Fossils
–
Part 1
What could these pictures in the rock
mean? You feel the rock and notice
that these are not drawings on top of
the rock…they appear to be
impressions of leaves and twigs in the
rock itself.
You ask a park ranger to explain what
you see. He tells you these are
fossils
- the preserved remains of
ancient organisms that once lived in
this area. He also says that
fossilization,
the process through
which a living thing becomes a fossil,
is quite rare.
This means that most living things do
not end up becoming fossils. It takes
millions of years for a living thing to
become a fossil, and there are lots of
different ways it can happen.

The type of fossil you are examining
is called a
mold
. This is when a
living thing is pressed into rock, the
living material decomposes, and an
impression is left behind. If there
had been small pieces of rock called
sediments
that filled these
impressions in the rock, they could
have cemented into another rock.
The fossil formed would be called a
cast
.
There is also a fossil type that does
not actually show the body of an
animal. In a
trace fossil
, an
animal’s footprint, feces, trail, or
burrow become fossilized. Examining
these types of fossils helps us learn
about an animal’s life.

Part 2
As the park ranger finishes
explaining how different types of
fossils are formed, you look around
the park and notice how much of the
landscape was formed by
erosion
–
the gradual wearing away of rocks
by wind, water, and other natural
events. These tiny sediments
gradually pile on top of dead animals
and cement together over time,
which is why most fossils are found
in
sedimentary rock
.
After all you’ve observed and
learned today, you’re thankful for a
beautiful park and all the wonders of
the past that can be revealed
through fossils!

On a research expedition to the Galapagos, you and your research team discover four new
species! All the animals appear to be chordates, but each animal has distinct traits:
Animal A: Both vertebral column and jaws
Animal B: Vertebral column, jaws, limbs and lays amniotic eggs (amniote)
Animal C: Vertebral column
Animal D: Vertebral column, jaws and limbs
A. Identify four derived characteristics that all chordates share.
B. Based on your understanding of phylogeny, map the animals and their traits onto the
phylogenetic tree provided below. In your response, list each number (1-8) and indicate which
trait or animal corresponds to that position on the phylogenetic tree.

Choose one of the following scenarios and answer the questions provided. Support your answers using scientific reasoning and discussing possible impacts to individuals, society, and the environment. Be sure to also discuss any medical or ethical issues that may apply. Scenario 1:Scientists have developed genetically engineered plants that are pest-resistant. By adding genes to the plant's DNA, they become toxic to insects (but not to plants or animals). This means that these plants may not need to be sprayed with pesticides to ward off the insects. Would you be willing to eat these genetically altered crops? Explain your answer. What are some possible impacts (positive or negative) of this genetically engineered plant on the environment, society, and individuals?

Hello, I need help answering number 8 a, b, & c using the phylogeny below. Pls & thank you!
8. a) As you know, the largest mass extinction in the history of life on earth was the Permian
extinction that occurred about 252 million years ago. The therapsids are often described as “mammal-like reptiles”.
If the Permian extinction had caused the extinction of the therapsids, would mammals as we know them now have evolved? Why or why not?
8. b) Many lines of evidence, including biochemical evidence, show that living birds are direct descendants of dinosaurs.
A number of dinosaur lineages had feathered dinosaurs, not just the lineage that includes living birds. Do you think that is it justified to believe that all feathered dinosaurs had behaviors known from living birds? Such behaviors of birds include colonial nesting, sexual displays by males using feathers, males moving to display their ornamental feathers to female mates. Give a brief reason for your answer.

THE FARMER AND THE FLY: PART II
Using the information from your explanation in Part I, the agricultural research facility
has set up a new program for controlling the fly population in the chicken houses. The
facility has purchased two additional insecticides, Formula B and C. These insecticides
are equally strong as Formula A, but have different chemical formulas. The facility has
set up the following program for using the three insecticides.
Program:
Year one: Use Formula A only
Year two: Use Formula B only (no A or C)
Year three: Use Formula C only (no B or A)
Use your knowledge of variation, evolution and natural selection to answer the following
questions.

Scientists find a fossil (Fossil A) in a deep layer of sedimentary rock. They determine that
Fossil A is the remains of a species never seen before. A few years later, other scientists
discover a similar fossil (Fossil B) in a layer of sedimentary rock closer to Earth's surface.
Fossil A and Fossil B share some characteristics, but it is determined that they are not closely
related and that Fossil B is a different species. One hundred years later, scientists discover
another similar fossil (Fossil C) in a layer of sedimentary rock between those in which Fossils
A and B were found. Upon examining all three fossils, scientists reach the conclusion that all
three fossils represent the same species. They determine that Fossil B (found in the shallowest
rock layer) evolved from Fossil C…

Please help with the following prompt using as much details as possible.
"One argument that is often made to invalidate evolution by natural selection is that some features of an organism are so complicated and need to work together in order to precisely function that it is impossible for such structures to arise from simpler ones by the random processes of mutation and selection: complicated design requires a designer. Using evidence from real organisms, explain how a complicated structure can arise from a simpler ancestral feature. You can use either an anatomical feature or molecular one."

P Flag question
Prior to the Industrial Revolution, the Biston betularia (peppered moth) was usually
white and light colored, and it blended in well among the pale lichens on the tree bark.
During and after the Industrial Revolution, the color of the moths gradually changed
from predominantly light-colored to black. What caused this change?
Select one:
O a. Black moths were able to camouflage themselves on the trees that had soot on the bark, but white moths
were eaten more by predators because they were not camouflaged.
O b. The bad pollution killed all of the white moths because they were not as strong as the black moths.
c.
Black moths grew stronger and ate all of the white moths, so the white moth population decreased.
O d. Black moths ate all of the pale lichens, so the…
