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.
What else can I help you with?
Are the legs of a cat and the fins of a whale homologous or analogous?
Neither. Homologous structures are similar because two organisms came from a common ancestor. Analogous structures are similar because two unrelated organisms were subjected to similar environments. But the legs of a cat and the fins of a whale are not similar enough to be characterized as either homologous or analogous. The ancestors of whales were hoofed mammals, and one could argue that a hoofed mammal's leg and a cat's leg are homologous. However, after millions of years of being in the oceans, whales' fins have adapted such that they are now not at all similar to the legs of a cat.
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.
What is homologouse structure?
A homologous structure is a structure found in two very different animals that has a similar form in both animals. For example, the bones of a human hand are homologous to the bones in a bat's wing or a whale's flipper. Structures that appear very similar suggest that two animal may be related, as in humans, bats, and whales, which are all mammals.
Are penguin flippers and bat wings homologous or analogous?
Yes they are. I disagree. Even if they ultimately come from a common ancestor, in order to classify two characteristics as homologous, they have to have some similarities. After millions of years of being in the oceans, the fins of whales have evolved such that they are not at all similar to cats' legs.
Analogous and homologous?
1. HOMOLOGOUS ( morphological and anatomical evidences ) .These are the organs that have same basic structural plan and origin but different functions. 2. ANALOGOUS These are the organs that have different origin and structure plan but same function
Homologous structure that is greatly reduced in size?
The pelvic bones in modern whales are an example of a homologous structure that has become greatly reduced in size. These bones are a remnant of the pelvis found in the common ancestor of whales and other mammals, but their size and function have been greatly reduced due to evolution and the adaptation of whales to an aquatic lifestyle.
Are whales and fish mammals?
Some whales are classified as mammals. Smaller fish are not
Are whales types of fish?
NO! They're mammals.
Are whales the largest mammals?
Yes, whales are the largest mammals.
Are Pilot Whales mammals?
Yes, pilot whales are mammals.
How many bones in whales flipper upper limb?
356
Are narwhals mammals?
Yes they are. Remember that Narwhals are whales, and that whales are most certainly mammals.
