All Flashcards
What is the effect of antibiotic use on bacterial populations?
Increased antibiotic resistance due to natural selection favoring resistant bacteria.
What is the effect of pesticide exposure on insect populations?
Evolution of pesticide resistance, leading to reduced effectiveness of the pesticide.
What is the effect of genomic changes in a population?
Can lead to new traits, adaptations, and potentially the formation of new species.
What is the effect of pathogen evolution?
Emergence of new diseases or re-emergence of old ones, posing threats to human health.
What is the effect of continuous change in the fossil record?
Provides evidence for the evolution of life over millions of years and the extinction of many species.
What are the differences between evolution at the individual level and the population level?
Individual: Changes within an organism's lifetime are not evolution. Population: Evolution is the change in the genetic makeup of a population over generations.
What is natural selection?
The process where organisms with advantageous traits are more likely to survive and reproduce, leading to changes in the population's genetic makeup over time.
Define evolution at the population level.
Change in the genetic composition of a population over successive generations.
What is antibiotic resistance?
The ability of bacteria to survive exposure to antibiotics that would normally kill or inhibit their growth.
What are genomic changes?
Alterations in the genetic material of an organism, including mutations, recombination, and changes in chromosome number.
Define pathogen evolution.
The rapid genetic changes in pathogens like viruses and bacteria, leading to new diseases or the re-emergence of old ones.
