Abigail, Ethan, and Nora are studying biology and they come across a concept that some organisms that share a common ancestor have features that have different functions, but similar structures. They are trying to remember the term for this concept. Can you help them?
vestigial structures
analogous structures
homologous structures
embryology
Abigail, Benjamin, and Jackson are on a virtual field trip to a zoo. They come across the Camelidae family members on their tour. They notice the physical features and the geographical origin of these animals. This observation provides evidence that -
they all live in the same type of environment.
they have slowly evolved to become herbivores.
they have a common ancestor.
they exchanged DNA in the past.
Kai, Anika, and Ava are having a debate about the changes of species over time. What is this process called?
Embryonic
Natural selection
Mimicry
Evolution
The tail bone, wisdom teeth, and appendix are all parts of the human anatomy that would be considered...
homologous structures
vestigial structures
fossils
extinct
Sharks, penguins, and dolphins all have fins but do not come from a common ancestor. What anatomical evidence does this prove?
Homologous
Analogous
Embryological
Vestigial
Elijah is studying different animals. He noticed that some animals, although they evolved from different ancestors, have similar functions due to living in similar environments. What is this phenomenon called?
Homologous structures
Analogous structures
Vestigial structures
All of the above
An anatomical feature that no longer seams to have a purpose in the current form of an organism
Homologous structure
Analogous structure
Vestigial structure
None of the above
A study of the body structures of animals to know how they evolved from the likes of their common ancestors for the purpose of adapting to their environment.
Evidence of Evolution
Comparative Anatomy
Fossils
Embryonic Development
What term describes the process by which different species evolve similar traits due to similar environmental pressures?
Divergent evolution
Convergent evolution
Parallel evolution
Co-evolution
Which of the following best describes homologous structures?
Structures that are no longer functional
Structures that have the same origin but different functions
Structures that have different origins but similar functions
Structures that are identical in all species
_____________ is the study of embryos. It can be used to see how embryo similarities and differences indicate an evolutionary relationship.
Paleontology
Common ancestry
Homologous structure
Embryology
True or False: embryos of species only look similar if their adult forms look similar
True
False
