What were the key environmental changes that occurred during the Great Oxygenation Event?
During the Great Oxygenation Event, key environmental changes included the significant increase in atmospheric oxygen levels, leading to the oxygenation of Earth's oceans and the formation of ozone layer in the atmosphere. This event occurred around 2.4 billion years ago and had a profound impact on the evolution of life on Earth.

Spontaneous changes in genetic material are called?
Spontaneous changes in genetic material are called mutations. These changes can occur naturally during DNA replication or as a result of environmental factors such as radiation or chemicals. Mutations can affect an organism's traits and may contribute to genetic diversity in a population.
What term describes all the changes that take place during the life of an organism including growth?
The term that describes all the changes that take place during the life of an organism, including growth, is "development." It encompasses physical, cognitive, emotional, and social changes that occur from conception to death. This process involves the interaction of both genetic and environmental factors.
Which group would most likely have the greatest survival success during a long period of environmental changes?
A diverse group with a wide range of traits and abilities would most likely have the greatest survival success during a long period of environmental changes. This diversity allows for greater adaptability to changing conditions and increased chances of at least some individuals surviving and reproducing.
Why do species evolve during adaptive radiation?
Species evolve during adaptive radiation to exploit new environmental niches and resources that become available. This allows them to diversify and specialize in different ecological roles, increasing their chances of survival and reproductive success. Adaptive radiation often occurs in response to significant environmental changes or when new habitats are colonized.
How do genes change over time and what factors contribute to these changes?
Genes change over time through mutations, which are alterations in the DNA sequence. Factors that contribute to these changes include environmental factors, such as exposure to radiation or chemicals, as well as errors that occur during DNA replication. Additionally, genetic recombination during sexual reproduction can also lead to genetic variation and changes in genes over time.
