Scientists and policy makers often have to work together to set catch limits on fisheries. Imagine
that a policy maker proposes to allow the fishing of
a certain species to go on at current rates
because, she says, “Fishing at current rates will
not impact the ecosystem. We are removing fish
at a rate lower than the birth rate of their
population." Is this claim valid? What indicators
would you look at to support or disprove this
claim? Explain your reasoning.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
