Transcript Selection-on-personality-presentation

Humans as a selective force
In this concurrent session, we will discuss some of the
many species that humans act as a selective force on, how
human selection occurs on those species, and the
evolutionary consequences had on those species. We will
then examine in detail how fishing can be a selective force,
which will include performing a fishing simulation.
Outline
• Discuss massive size of human population and the increasingly
large role we play in how the earth functions.
– One such role being that of a selective force
• Two types of human driven selection
– Artificial selection: Humans intentionally select for certain traits (crops,
livestock, horses, etc)
• Discuss targets of selection, what is needed for evolution to take place, and
evolutionary consequences for the different examples
– Natural selection: Humans unintentionally select for certain traits, either
directly or indirectly through their actions (hunting, fishing, habitat
modification, global warming, etc.)
• Discuss targets of selection, what is needed for evolution to take place, and
evolutionary consequences for the different examples
• Specific example with selection on fish personality
– Do activity
– Discuss activity
