Homologies and analogies – Understanding Evolution
We use homologous characters — characters in different organisms that are similar because they were inherited from a common ancestor that also had that character. An example of homologous characters is the four limbs of tetrapods. Birds, bats, mice, and crocodiles all have four limbs. Sharks and bony fish do not.

Birds and crocodiles, seemingly disparate creatures, share a stunning link that can be traced to a shared evolutionary origin. With over 10,000 species of birds and 14 species of crocodiles, these two groups belong to the larger class of reptiles known as Archosaurs.

31 oct. 2023Figure 18.5F. 1 18.5 F. 1: Homology vs. analogy: The wings of pterosaurs (1), bats (2), and birds (3) are analogous as wings, but homologous as forelimbs. This is because they are similar characteristically and even functionally, but evolved from different ancestral roots. Paralogous genes often belong to the same species, but not always.

31 juill. 2022Similar traits can be either homologous or analogous. 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 …

Birds and crocodiles both provide parental care to their offspring, as shown below. Crocodiles and birds share a number of adaptations that allow them to survive in the harsh environment of the deep sea. For example, crocodilians have a thick skin that protects them from the cold, while birds have feathers that help them keep warm.

The UC Santa Cruz team used the crocodilian genomes, combined with newly published bird genomes, to reconstruct a partial genome of the common ancestor of crocodiles, birds, and dinosaurs. The study, part of an ambitious international collaboration to analyze the genomes of modern birds and gain insights into their evolution, is one of eight …

Homologies: Anatomical evidence. Organisms that are closely related to one another share many anatomical similarities. Sometimes the similarities are conspicuous, as between crocodiles and alligators. In other cases – particularly when lineages have experienced natural selection shaping them in different ways – more study is needed for a …
