History of Life on Earth (General Biology 2, 1st Semester, Quarter 1, Week 2A)RheaGulay3
Describe general features of the history of life on Earth, including generally accepted dates
and sequences of the geologic time scale and characteristics of major groups of organisms
present during these periods (STEM-BIO11/12-IIIC-G-8).
Specific Objectives:
1. Identify the date, eon, era, period, epoch and describe the major events base on
Geologic Time Scale.
2. Differentiate the types of fossils.
3. Appreciate the history of life on earth by making a personal timeline.
This slide presentation aims to help teachers and students in studying biodiversity and evolution. It consists of images, definition of terms all related to biodiversity and evolution.
A fossil is the preserved remains of a once-living organism.
Fossils give clues about organisms that lived long ago. They help to show that evolution has occurred.
They also provide evidence about how Earth’s surface has changed over time.
Fossils help scientists understand what past environments may have been like.

The simplified electron and muon model, Oscillating Spacetime: The Foundation...RitikBhardwaj56
Discover the Simplified Electron and Muon Model: A New Wave-Based Approach to Understanding Particles delves into a groundbreaking theory that presents electrons and muons as rotating soliton waves within oscillating spacetime. Geared towards students, researchers, and science buffs, this book breaks down complex ideas into simple explanations. It covers topics such as electron waves, temporal dynamics, and the implications of this model on particle physics. With clear illustrations and easy-to-follow explanations, readers will gain a new outlook on the universe's fundamental nature.
How to Build a Module in Odoo 17 Using the Scaffold MethodCeline George
Odoo provides an option for creating a module by using a single line command. By using this command the user can make a whole structure of a module. It is very easy for a beginner to make a module. There is no need to make each file manually. This slide will show how to create a module using the scaffold method.
This presentation was provided by Steph Pollock of The American Psychological Association’s Journals Program, and Damita Snow, of The American Society of Civil Engineers (ASCE), for the initial session of NISO's 2024 Training Series "DEIA in the Scholarly Landscape." Session One: 'Setting Expectations: a DEIA Primer,' was held June 6, 2024.
2. What is a fossil?
•
A fossil is the preserved remains of a onceliving organism.
What do fossils tell us?
• Fossils give clues about organisms that lived
long ago. They help to show that evolution has
occurred.
• They also provide evidence about how Earth’s
surface has changed over time.
• Fossils help scientists understand what past
environments may have been like.
3. HOW IS A FOSSIL FORMED?
1. Sediment
2. Layers
3. Movement
An animal is buried by
sediment, such as
volcanic ash or silt,
shortly after it dies. Its
bones are protected
from rotting by the
layer of sediment.
More sediment layers
accumulate above the
animal’s remains, and
minerals, such as
silica (a compound of
silicon and oxygen),
slowly replace the
calcium phosphate in
the bones.
Movement of tectonic
plates, or giant rock
slabs that make up
Earth’s surface, lifts
up the sediments and
pushes the fossil
closer to the surface.
4. Erosion
Erosion from rain,
rivers, and wind wears
away the remaining
rock layers. Eventually,
erosion or people
digging for fossils will
expose the preserved
remains.
4. SIX MAIN TYPES OF FOSSILS
Petrified
Fossils
Molds
Casts
Carbon
Films
Trace
Fossils
Preserved
Remains
5. PETRIFIED FOSSILS
• The word “petrified” means
“turning into stone.”
• Petrified fossils form when
minerals replace all or part
of an organism.
PETRIFIED FOSSIL
The Field Museum in Chicago
displays a fossil of a
Tyrannosaurus rex.
• Water is full of dissolved
minerals. It seeps through
the layers of sediment to
reach the dead organism.
When the water evaporates,
only the hardened minerals
are left behind.
6. MOLDS AND CASTS
• A mold forms when hard parts of an
organism are buried in sediment, such as
sand, silt, or clay.
MOLD FOSSIL
This mold, or imprint, is of an
extinct mollusk called an
ammonite.
• The hard parts completely dissolve over
time, leaving behind a hollow area with
the organism’s shape.
• A cast forms as the result of a mold.
• Water with dissolved minerals and
sediment fills the mold’s empty
spaces.
CAST FOSSIL
This ammonite cast was
discovered in the United
Kingdom.
• Minerals and sediment that are left
in the mold make a cast.
• A cast is the opposite of its mold.
7. CARBON FILMS
• All living things contain an
element called carbon.
• When an organism dies
and is buried in sediment,
the materials that make up
the organism break down.
FERN FOSSIL
This carbon-film fossil of a
fern is more than
300 million years old.
• Eventually, only carbon
remains.
• The thin layer of carbon
left behind can show an
organism’s delicate parts,
like leaves on a plant.
8. TRACE FOSSILS
• Trace fossils show the
activities of organisms.
• An animal makes a footprint
when it steps in sand or mud.
FANCY FOOTWORK
This dinosaur footprint was
found in Namibia, Africa.
• Over time the footprint is
buried in layers of sediment.
Then, the sediment becomes
solid rock.
9. PRESERVED REMAINS
Some organisms get preserved in or close to their
original states. Here are some ways that can happen.
Amber
An organism,
such as an insect,
is trapped in a
tree’s sticky resin
and dies. More
resin covers it,
sealing the insect
inside. It hardens
into amber.
Tar
An organism,
such as a
mammoth, is
trapped in a tar pit
and dies. The tar
soaks into its
bones and stops
the bones from
decaying.
Ice
An organism,
such as a woolly
mammoth, dies in
a very cold region.
Its body is frozen
in ice, which
preserves the
organism—even
its hair!
