Question

siblings have similar traits because they inherit those traits from a common ancestor. how is this similar to some evidence for evolution? there are many differences between related organisms, which shows common ancestry. similarities can be seen between siblings in species today, which shows common ancestry. similarities can be seen among related organisms, which shows common ancestry. there are many differences between siblings in species today, which shows common ancestry.

Explanation:

To solve this, we analyze each option:

• The first option talks about differences between related organisms showing common ancestry, but differences don't directly indicate common ancestry (similarities do).
• The second option mentions similarities between siblings in species today, but the evidence for evolution's common ancestry is about related organisms (not just siblings in a species) having similarities.
• The third option: Similarities among related organisms (like how siblings have similar traits from a common ancestor) is analogous to evidence for evolution, where related organisms' similarities suggest common ancestry.
• The fourth option talks about differences between siblings showing common ancestry, which is incorrect as differences don't imply common ancestry in this context.

Answer:

The correct option is: "Similarities can be seen among related organisms, which shows common ancestry." (the third option among the four, assuming the four are ordered as: first top-left, second top-right, third bottom-left, fourth bottom-right)
