Organisms can ONLY be considered a different "new" species once they:

have a different appearance from each other.

no longer mate with each other.

can no longer produce fertile offspring.

find each others appearance and behavior a little strange.

Answer 1

To determine if organisms can be classified as a different "new" species, the following criteria are relevant:

1. No longer mate with each other.
2. Can no longer produce fertile offspring.

The first statement is significant because reproductive isolation is a key factor in defining species. If two groups can no longer mate successfully, it suggests they have diverged enough genetically or behaviorally to be considered separate species.

The second statement reinforces this by emphasizing that being able to produce fertile offspring is important; if two groups can mate but produce sterile offspring, they are often considered separate species.

The other options (different appearance and finding each other's behavior strange) can be associated with species differentiation but are not definitive criteria for defining a new species. Appearance can vary within a species, and behavior may not significantly impact reproductive isolation.

Therefore, the correct answers are:

• No longer mate with each other.
• Can no longer produce fertile offspring.
