At the molecular level, how do scientists know a new species has arisen?
Answer:
DNA sequencing has brought us the genetic species concept. In this model, species are defined by genetic isolation rather than reproductive isolation. Species may be more or less identical morphologically, but differences in DNA determine whether or not a population is a new species.

The graph shows the change in seabird mortality rates in New Zealand waters due to illegal, unreported, and unregulated fishing (IUU) and the implementation of bycatch remediation measures in 2004. What conclusion can be made about the impact of the remediation measures that were used?
Illegal and unregulated fishing practices continue to cause increases in bird bycatch numbers, in spite of the new measures.
Legal fishing practices have caused the new remediation measures to become more effective.
The measures virtually eliminated all of the bird bycatch.
The measures used showed very little impact on the overall seabirds caught in fishing lines.
According to the graph, the measurements practically eliminated all incidental captures, as shown in the third answer option.
What does the graph show?Illegal capture practices show a high performance between 1997 and 2003.Illegal capture practices show a low performance from 2004 and this performance tends to fall in the next years until it presents very low values.Legal capture practices maintain a balanced performance.The decrease in the performance of illegal practices from 2004 onwards, shows how the remediation measures were efficient in reducing the activity of these practices and providing a better environmental well-being.
