What else can I help you with?
Both homologous and analogous forms of these result from evolution?
Structures
What are analogous structures?
Analogous structures are features of two different species that are similar in how the function, but the structure of the two features is different. The wings of an insect and the wings of a bird are analogous structures.
What term describes parts of organisms that have a similar function but not a similar structure?
Analogous structures are body parts that have a similar function in different species but have evolved separately, thus not sharing a common ancestor. These structures result from convergent evolution, where organisms adapt to similar environmental pressures.
What are analogous characteristics?
Analogous characteristics are traits or features that are similar in function or purpose but have different evolutionary origins. For example, the wings of birds and insects are analogous structures because they both serve the function of flight, but have evolved independently in each group.
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 are similar structures that evolve independently?
Similar structures that evolved independently are called analogous structures, or analogies.
Is the concept of convergence related to the notion of analogous structures?
no
What do the structures that result from convergent evolution indicate about organisms?
The structure that result from convergent evolution indicates that organisms have to be reclassified because when scientists compared nucleic acid from the cells of the animals and they found many diffrences in them.
How are analogous and homologous structures different?
They are different because homologous structures have the same structure, but serve a different function. Like mammal arms(human, bat and whales). Analogous structues are different structures, but serve the same function. For example, bat wings and butterfly wings.
Rhizoids in molds are analogous to which structures on plants?
Rhizoids in molds are analogous to roots in plants. They both serve as structures that anchor the organism in place and aid in absorbing nutrients from the environment.
What is the difference between homologous structures and analogous structures?
Homologous = same origin, different function (arms vs. wings) Analogous = same function, different origin (panda thumb)
If Whales and cats are both mammals Are the whale's front flipper and the cat's front leg homologous or analogous and why?
Neither one. Both homologous and analogous structures refer to similar structures. But a cat's front leg and a whale's front flipper have little in common. Homologous structures come from little evolutionary separation, and analogous structures come from convergent evolution. But the differences between a cat's front legs and a whale's front flipper result from divergent evolution. The common ancestor of mammals (cynodonts) has split into various groups with widely differing characteristics. One such group includes cats, and another includes whales. These two groups are not very related to each other, thus having no homologous structures, and have been put in very different environments, thus having no analogous structures.
