evolution
What is evolution?
the change in the characteristics of a species over several generations and relies on the process of natural selection
what is Environmental issues
climent change,deforastation,invasiv species
What can fossils tell us?
the history of life on Earth, including how organisms evolved, what ancient ecosystems were like, the climates of past eras, and how living things adapted to environmental changes over time
Is a chameleon's color matching the leaves in a tree a structural or behavioral adaptation
what is natural selection
the process by which organisms with traits that better suit their environment are more likely to survive and reproduce, passing on those advantageous traits to future generations, leading to a gradual change in the population over time
what is environmental issues that happend a long time ago
soil erosion, overgrazing, overfishing, water pollution from waste disposal, air pollution from burning wood and other fuels in cities, and the depletion of local resources due to unsustainable practices in ancient civilizations like the Greeks, Romans, and Egyptians
What are some problems with the fossil record?
What are the two main types of adaptation
structural adaptations (physical features of an organism) and behavioral adaptations (actions an organism takes to survive in its environment)
How does evolution work?
Through a process called natural selection, where organisms with advantageous traits, caused by genetic variations, are more likely to survive and reproduce, passing on those beneficial traits to their offspring, leading to gradual changes in a population over generations, adapting them to their environment
what is Environmental science
an interdisciplinary field that studies the environment and how to solve environmental
What can we learn from the fossil record about evolution?
demonstrating how life forms have changed over time, showcasing the progression of species, revealing the existence of transitional fossils between different groups, and indicating the relationships between extinct and living organisms
Are webbed feet a structural or behavioral adaptation
Webbed feet are considered a structural adaptation because they are a physical feature of an organism, specifically the webbing between the toes, which allows for better swimming ability and is not a behavior the animal chooses to perform; it's a built-in characteristic that helps it survive in its environment
How does evolution affect species?
Causing gradual changes in their characteristics over time, allowing them to adapt better to their environment through natural selection
what is inviormental ethics
a branch of philosophy that studies the moral relationship between humans and the environmen
How do fossils form?
when a dead organism, like a plant or animal, is rapidly buried by sediment (like mud, sand, or volcanic ash), which prevents decomposition, and over time, minerals from the surrounding water seep into the remains, replacing the organic material and hardening into rock, essentially creating a preserved "copy" of the original organism
How do physical and behavioral traits help animals survive
providing them with specific characteristics that allow them to find food, protect themselves from predators, cope with their environment's challenges, and successfully reproduce within their habitat
what is origin of the Genetic Code
the process by which organisms with traits that better suit their environment are more likely to survive and reproduce, passing on those advantageous traits to future generations, leading to a gradual change in the population over time
Environmental policy
any measure by a government or corporation or other public or private organization regarding the effects of human activities on the environment
What are the different types of fossils?
petrified fossils, mold and cast fossils, carbon film fossils, trace fossils, preserved remains, compression fossils, impression fossils, and pseudo fossils.
How do the structures and functions of living things allow them to meet their needs
the specific shape and design of an organism's parts directly relate to what functions they can perform to stay alive
