Question

Explain homologous structures. Someone pls help

Answer 1

Step-by-step explanation:

Homologous structures refer to structures in different species that have a similar appearance, structure, and function, but have evolved independently. These structures are evidence of a common ancestry, as they indicate that the species share a common evolutionary history.

For example, the bones in the forelimbs of humans, birds, and bats all have a similar structure and arrangement, but have evolved differently to adapt to different environments and lifestyles. Despite these differences, the bones in the forelimbs of these species are still considered homologous structures because they have a common ancestry and evolved from a similar ancestral structure.

Homologous structures can provide valuable information about the evolutionary relationships between species and the processes of evolution. By studying the similarities and differences in these structures, scientists can gain insights into how species have evolved over time and how they are related to one another.

Answer 2

They are the bodily parts of different species that, through evolution, have developed from ancestors with comparable characteristics.

For instance, the wings of bats and the arms of primates are two typical examples of homologous features in evolutionary biology. Genetically, despite the fact that these two structures do not resemble one another or perform the same function, they are descended from the same last common ancestor structure.
