What is the effect of a physical barrier on a population?
It can lead to allopatric speciation if the barrier prevents interbreeding.
How can different breeding times cause speciation?
Populations may undergo sympatric speciation if they breed at different times, preventing interbreeding.
What is the effect of climate change on species adaptation?
Climate change creates environmental pressures that force species to adapt or face extinction.
What is the effect of habitat fragmentation on species evolution?
Habitat fragmentation can isolate populations, leading to different evolutionary paths and potentially speciation.
Define adaptation.
Process where species change over time to better fit their environment through genetic, behavioral, or physiological changes.
Define evolution.
The change in the heritable characteristics of biological populations over successive generations.
Define allopatric speciation.
Speciation that occurs when a physical barrier prevents two populations from interbreeding.
Define sympatric speciation.
Speciation that occurs when populations in the same area stop reproducing due to different breeding times, seasons, or incompatibilities.
Define reproductive isolation.
When two populations can no longer interbreed, leading to the formation of separate species.
Define genetic diversity.
The variety of genes within a population or species.
What is 'survival of the fittest'?
Having the genes that best match the environment, increasing the likelihood of thriving and passing those genes on.
What is the role of environmental pressures in adaptation?
Environmental pressures like climate change, competition, and predators drive adaptation by favoring certain traits.
Why is genetic diversity important for a population's survival?
Populations with diverse genes are more resilient to disasters and environmental changes.
How do ecosystems drive evolution?
Environments are always shifting, and to survive, populations must keep up with these changes through evolution.
What happens if a population doesn't adapt to environmental changes?
It faces higher death rates and the risk of extinction.
What are the three types of adaptations?
Genetic, behavioral, and physiological.
