The same kinds of cells that grow in similar patterns in different but related organisms produce?
homologous structures. These structures indicate common ancestry and are evidence for evolution. Examples include the wing of a bird and the flipper of a dolphin.
How do homologous structures among animals provide evidence for evolution?
Homologous structures among animals are similar body parts that suggest a common ancestry. These structures provide evidence for evolution because they indicate that different species share a common evolutionary history and have evolved from a common ancestor.
How are homologous evidence for evolution?
Homologous structures are evidence for evolution because they indicate that different species share a common evolutionary ancestor. These structures have similar underlying anatomical or genetic features, suggesting a shared evolutionary history. For example, the bones in the limbs of vertebrates all share a common anatomical structure, indicating a shared evolutionary origin.
What is the difference between analogous and homologous?
Analogous means that the structures have different origins, but they do the same things. Homologous means the opposite: that they have the same origins but are adapted to do different functions.
What are 3 forms of evidence for evolution?
Fossil record: Shows a gradual change in species over time, supporting the idea of common ancestry and evolution. Genetic evidence: Similarities in DNA sequences between different species indicate shared ancestry and evolutionary relationships. Comparative anatomy: Homologous structures among different species suggest a common origin and evolution from a common ancestor.

How do vestigial structures indicate that present day organisms are different from their ancient ancestors?
Vestigial structures are remnants of organs or features that were functional in an organism's ancestors but have reduced or lost their original function over time. The presence of these structures suggests that present-day organisms have undergone evolutionary changes from their ancient ancestors. These structures provide evidence for common ancestry and support the theory of evolution.
What is an explanation of why bird wings and reptile forelegs are evidence of evolution?
Homologous structures indicate a common ancestor
How do homologous structures among animals provide evidence for evolution?
Homologous structures among animals are similar body parts that suggest a common ancestry. These structures provide evidence for evolution because they indicate that different species share a common evolutionary history and have evolved from a common ancestor.
What does the prefix homo mean in biology?
In biology, the prefix "homo-" means "same" or "similar." It is often used to indicate similarity or sameness among organisms or structures, such as in the term "homologous structures" to describe similar structures in different species.
Why is the existence of vestigial structures significant to study of evolution?
The existence of vestigial structures is significant to the study of evolution because they provide evidence of an organism's ancestral lineage and indicate how species have adapted over time. These structures, which have lost their original function, suggest that evolutionary processes lead to changes in anatomy and functionality in response to environmental pressures. By studying these remnants, scientists can trace evolutionary paths and better understand the mechanisms of natural selection and adaptation. Overall, vestigial structures highlight the dynamic nature of evolution and the relationship between different species.
Compare homologous and analogous structures?
Homologous structures are structures that indicate a related evolutionary ancestry, not just similarity. For example, the flipper of a whale, the wing of a bird, and the arm of a a human are similar in their bone structure. Analogous structures are structures that are similar in appearance and function but are not the result of shared ancestry. For example, the wings of a birds and insects have the same function, but they do not reflect a shared ancestry.
What do similarities between amino acid sequences indicate?
Similar amino acid sequences can indicate similar protein structure and function. Hydrophobic residues will orient the same way in solution as will polar residues. Charged amino acids are commonly found within or near the active sites enzymes. Similar amino acid sequence can also indicate a similar evolutionary origin known as convergent evolution. This is the same for unique proteins that evolved from a common ancestral protein which is known as divergent evolution.
What is placed between a molecule's resonance structures to indicate resonance?
Usually two way arrows are placed between a molecule's resonance structures to indicate resonance
How are homologous evidence for evolution?
Homologous structures are evidence for evolution because they indicate that different species share a common evolutionary ancestor. These structures have similar underlying anatomical or genetic features, suggesting a shared evolutionary history. For example, the bones in the limbs of vertebrates all share a common anatomical structure, indicating a shared evolutionary origin.
How can the relatedness of very dissimilar organisms be determined?
The relatedness of very dissimilar organisms can be determined by comparing their genetic material, such as DNA or RNA sequences. By analyzing these sequences, scientists can identify similarities and differences that can indicate how closely or distantly two organisms are related in terms of evolution. Additionally, studying shared characteristics, such as anatomy or biochemistry, can also provide insights into the relatedness of organisms.
What do homologous structures indicate?
that we share a common ancestor
