Better Evolution Flashcards
How do survival rates differ for successful adaption?
Organisms with successful adaptions have higher survival rates because they are better suited to their environment
How have organisms changed over time ? Give an example
Organisms evolve over time to adapt to changing environments.
EXAMPLES: Darwin’s finches developed different beaks to suit their environment available food on each island
What is a simple evolutionary sequence
- Variation in a species show
- Competition for resources
- Survival of those with beneficial traits
4.successful traits get passes down
- Evolution occurs over many generations
What is meant by peer review ?
Peer review is when scientists check each others work to ensure it’s correct and reliable before it’s published
What is the process by which organisms evolve?
Natural selection is the process by which organisms with traits that help them survive are more likely to reproduce and pass those traits on
What does the term extinct mean
A species is extinct when there are no more living individuals of that species on earth
What is biodiversity
Biodiversity refers to the variety of different species in an area , including plants , animals , and microorganisms
What is a possible theory for dinosaur extinction?
One theory is the asteroid impacts , where a huge asteroid hit earth , causing massive climate change s like darkness and cold , which led to the extinction of dinosaurs
What is meant by an endangered species
An endangered species is a species at risk of becoming extinct in the near future due to factors like habitat loss or over hunting
Name one way of protecting endangered species
Creating protected areas like wildlife reserves or national parks helps protect endangered species from threats like hunting and habitat destruction
How can you identify simple patterns in data?
Look for trends or relationships in the data , such as when an increase in one factor ( e.g , temperature) leads to a decrease (e.g , tree numbers )
