Natural Selection And Gentic Modification Flashcards
What are the benefits of selection pressures
Make individuals better adapted to their environment
Gives a higher chance of survival and reproduction
What will happen to the more adapted and less adapted organisms?
The good characteristics become popular over time
less adapted to the selection pressures will be less able to compete
How does antibiotic resistance provide evidence for evolution?
Because it makes the bacteria better adapted to an environment in which antibiotics ( a selection pressure) is present
What does it tell us about the age of a rock if it is buried deeper underground?
It’s older, the deeper the rock the older the fossil
Who came up with the theory of evolution and natural selection?
Charles Darwin
Other than Charles Darwin, who contributed to the theory of evolution and natural selection?
Alfered Russel Wallace
What did genetic diversity help changing environments ?
It can help populations adapt to changing environments
What is Darwin’s theory of evolution in stages?
CHANGE of environment identified VARIATION within the species STRUGGLE of survival due to limited resources NATURAL selection “survival of fittest” REPRODUCTION of the best adapted species EVOLUTION of new species
What does the evolution of stone tools suggest about evolution
As they became more complex, their brains must of been getting larger
How can you tell how old fossil is
The structural features of a fossil example simple tools are more older than advanced
Stratigraphy- study of rock layers
What is the order of the classification system
Domain, kingdom, Phylum, class, order, family, genus, species.
What are the five kingdom groups called?
Animals plants fungi prokaryotes plants protists
What are the prokaryotes
Single celled organisms without a nucleus
What are protists?
Eukaryotic single celled organisms
What is a eukaryote ?
Includes protists fungi plants and animals
