Which of the following, about homologous traits, is true? A. The wings of bats and birds are homologous traits. B. Behaviors of animals can not be considered to be homologous traits. C. Homologous traits are also referred to as "derived traits". D. A homologous trait is shared by two or more species and is inherited from a common ancestor. E. DNA and protein sequences can not be considered to be homologous traits.

### D. A homologous trait is shared by two or more species and is inherited from a common ancestor.

## Step1: Understanding Homologous Traits### Homologous traits are characteristics that are shared by two or more species because they were inherited from a common ancestor. These traits can be structural, physiological, or molecular.## Step2: Analyzing the Options### Option A suggests that the wings of bats and birds are homologous traits. While both have wings, they are not homologous because they evolved independently in different lineages. Option B is incorrect because behaviors can indeed be homologous traits. Option C is incorrect because derived traits are those that have evolved in a lineage after the split from a common ancestor, not necessarily homologous. Option E is incorrect because DNA and protein sequences can be considered homologous if they are similar due to common ancestry.## Step3: Identifying the Correct Statement### Option D correctly states that a homologous trait is shared by two or more species and is inherited from a common ancestor, which aligns with the definition of homologous traits.
