What Is Analogous In Biology

What Is Analogous In Biology?

analogy in biology similarity of function and superficial resemblance of structures that have different origins. For example the wings of a fly a moth and a bird are analogous because they developed independently as adaptations to a common function—flying.

What is analogous and homologous?

Homologous structures share a similar embryonic origin analogous organs have a similar function. For example the bones in the front flipper of a whale are homologous to the bones in the human arm. These structures are not analogous. The wings of a butterfly and the wings of a bird are analogous but not homologous.

What does analogous mean in evolution?

In evolutionary biology the meaning of analogous is “having similarities in functions but different evolutionary origins”. In other words different species with different evolutionary lines use their biological structures for the same purpose. This type of evolution is termed convergent evolution.

What does analogous mean in chemistry?

What is an example of an analogy?

Abstract. Analogical reasoning is a kind of reasoning that is based on finding a common relational system between two situations exemplars or domains. When such a common system can be found then what is known about one situation can be used to infer new information about the other.
