Question

multiple-choice question
which is true about the speciation of finches?
one species migrated from ecuador, then over many years, evolved into the 13 different species in galapagos, due to different selective forces on each island.
different species evolved in ecuador, then flew to the galapagos islands to find the perfect habitat.
rewatch

Explanation:

To determine the correct statement about finch speciation, we analyze the options:

• The first option aligns with the theory of adaptive radiation. A single finch species migrated from the mainland (Ecuador) to the Galapagos Islands. Over time, different selective pressures (like food availability, habitat) on each island led to natural selection, causing the species to evolve into 13 distinct species.
• The second option is incorrect because finches did not evolve into different species in Ecuador first and then fly to Galapagos; the speciation occurred in the Galapagos due to island - specific selection.

Answer:

A. One species migrated from Ecuador, then over many years, evolved into the 13 different species in Galapagos, due to different selective forces on each island.
