Sister species of palm trees on Lord Howe island in the Tasman Sea between Australia and New Zealand are an example of potential sympatric speciation. These species are both wind pollinated, which increases potential for gene flow within the island. However, there is little evidence of gene flow between these two palm tree species. Upon closer investigation, flowering time of the palm tree species (reproductive season) is separated by 6 weeks. What would you expect to happen if a major mutation in one palm species shifted the flowering time to be coincident (occurring at the same time) with the other palm species

What evidence could be used to convince policy makers to change a shipping lane from going through a whale breeding ground? information on the number of all whale species currently alive information on the number of all whales hit by boats in the given area information on the number of whale deaths in the world's oceans information on the number of whale offspring born every year. (a) scientists could collect and combine data on fish populations all around the world to show that their populations are declining. (b) scientists collect and combine data on fish populations all around the world to show that their populations are increasing. (c) scientists work together and use past data to show that fish populations are becoming locally extinct in some areas. (d) scientists work together and use past data to show that some fish populations are adapting to environmental changes.
