Answer: Genetic Drift
Explanation: Genetic drift is an evolutionary mechanism whereby gene or allele frequency of a particular population change over generations due to random chance. The effect of genetic drift is most visible in small population due to reduction in population size resulting from natural disaster or splitting of a small group from the main population to formation a colony. However, it can occur in large population as well but it's effect is as strong as that occurring within a small population.
The genetic drift among the Dunkers could be attributed to the official split between conservatives and progressives members in 1882.
Answer:
Paul Snelgrove states that oceans contribute significantly to, not *only* sustaining life on Earth, but they are play a crucial part in nutrient cycling, food, and oxygen, and also influence the weather. As it is all connected, without oceans, there is no life.
Explanation:
The biological diversity that the planet's oceans host are crucial for life on Earth as it provides immense benefits to humans. Dr. Paul Snelgrove states that these bodies of water sustain this biodiversity, enhance fisheries, protect and conserve habitats, amongst an innumerable amount of benefits.
From seafloor environments to the pelagic sea, every habitat and each species of the ocean play an essential role and a wide range of functions in the mainteinance of a healthy and sustainable planet.
According to Dr. Snelgrove, without thorough global management, human activities that affect biodiversity will not only affect the most vulnerable human populations and marine habitats, but will have a strong, negative impact on health, hygiene, food security, and economy.
