Answer:
The correct answer is- adaptive radiation
Explanation:
Adaptive radiation is the evolutionary process which allow the evolution of many species from a single species because some population of that species get into an environment which is different from their old environment in terms of food availability, predators, etc.
So the first bird that evolved the ability to fly branched into many different species due to habitat change is an example of adaptive radiation. The most famous example of adaptive radiation is Darwinian finches which evolved from an ancestral species of south America that reached Galapagos island.
Answer:
- The Island population likely has fewer alleles-that is versions of genes-than the mainland population.
A- Agree <u>B- Disagree</u>
- Genetic drift is more pronounced in the island population than in the mainland population in these first few generations
A- Agree <u>B- Disagree</u>
- Some harmful traits may have become more common in the island population than in the mainland population
<u>A- Agree</u>- B- Disagree
- Biologist observed genetic drift but not evolution
<u>A- Agree</u> B- Disagree
Explanation:
If there was genetic drift, then allele frequency either increased or decreased by chance, irrespective of natural selection that is irrespective to weather those alleles helped individuals survive in the island environment. In molecular genetic data, there are statistical signature in the population variation that indicate weather selection or other processes occurred.
