BIODIVERSITY AND EVOLUTION Flashcards
refers to the variety of life forms on earth.
Biodiversity
Three types of Biodiversity
Species Diversity
Ecosystem Diversity
Genetic Diversity
The process by which species
change over time through
mechanisms like natural
selection, genetic mutations,
and adaptation.
Evolution

Fossil Records
Biochemical evidence
Comparative Morphology and Anatomy
Observable Events
A PROCESS THAT CAUSES SPECIES TO CHANGE OVER
TIME BY FAVORING THE SURVIVAL AND REPRODUCTION
OF ORGANISMS THAT ARE BEST ADAPTED TO THEIR
ENVIRONMENT
natural selection
Key points about Natural Selection
- Variation
- Struggle for Survival
- Survival of the fittest
- Adaptation
a process where
humans intentionally breed plants or animals to
produce specific traits.
Artificial Breeding
Another term for artificial breeding
selective breeding
Key features of Artificial
Human intervention
Rapid Changes
Purposeful
the evolutionary process by which populations
of a single species diverge to form new, distinct species.
Speciation
