Evolution Basics
This person came up with the theory of evolution
Charles Darwin
As the Earth cooled, water vapor condensed to form
Oceans
Life on Earth started
3.5 billion years ago
We have had_____mass extinctions
5
These provide evidence of past life and evolutionary changes
Fossils
These are the islands that Charles Darwin observed diverse species
Galapagos Islands
This is causing the Earth to heat up
Global warming
The Earth formed about ______ years ago from dust and gas in the solar nebula.
4.5 billion years ago
This is known for the emergence of multicellular organisms era
Late Precambrian period
Fossils are...
preserved remains or traces of ancient organisms
This is the process by which species change over time.
Evolution
Variations is
Individuals in a population have different traits.
This formed the atmosphere
Intense volcanic activity releasing gases
This lasted from about 541 to 252 million years ago. It is known for the emergence of diverse marine life and the first land plants.
Paleozoic
The four types of fossils are
mold, cast, trace, and true form.
This is a key mechanism driving evolution, where organisms better adapted to their environment survive and reproduce.
Natural selection
Competition is
when organisms compete for limited resources.
The early Earth was
Extremely hot and had a molten surface.
This spanned from about 252 to 66 million years ago. This era is often called the "Age of Reptiles" due to the dominance of dinosaurs.
Mesozoic
Fossils can help us predict
the future of organisms
This heavily influences the evolution of species as temperatures increase
Climate Change
Adaption is when
Traits are enhanced for survival become more common.
This was the living organism on Earth
Prokaryotic cells
This began around 66 million years ago.It is characterized by the rise of mammals and birds after the extinction of dinosaurs.
Cenozoic
WHAT IS THE DEFINITION OF BIOLOGY
the study of life
