Homologous organs are similar in structure and origin but may differ in function, whereas analogous organs have similar functions but different origins and structures. Homologous organs suggest a common evolutionary ancestry, while analogous organs are a result of convergent evolution.
Homologous organs have similar looking structure and similar origin but different functions . Whereas analogous is just the opposite analogous organs are those that have similar function but different origin and structure
Vestigial Organs
A synapsis is the pairing of 2 homologous chromosomes.
Shared evolutionary origin: Organs must have a common ancestral structure that has been modified over time. Similar structural organization: Homologous organs should have similar basic structure and pattern of development. Similar function: Although homologous organs may have different functions in different species, they should share a common underlying function or purpose.
Yes, the nails of a man and claw of a cat are homologous organs with similar structure but performs functions differently.
a. the presence of homologous structures b. the presence of vestigial organs
Those organs are called vestigial organs. They are remnants of functional structures that were more developed in ancestral species but have decreased in size or usefulness in the current organism.
Using your mouth and tongue to stimulate your partners sex organs.
Analogous structures are those that have similar functions but different evolutionary origins, whereas homologous structures are those that have different functions but a common evolutionary origin. For example, the wings of bats and birds are analogous structures as they serve the same function (flight) but evolved separately, while the forelimbs of humans, cats, and whales are homologous structures as they have a common evolutionary origin (from a common ancestor) but serve different functions.
