birds and mammals are both endothermic. i.e. they maintain body temperature internally through metabolism rather than from the environment. how would you explain this, given the position of the two groups of animals on the phylogenetic tree?

Sagot :

On the phylogenetic tree, (a diagram used to show relatedness among organisms) the birds and mammals are closely related to each other and they both are characterized as endothermic.

Given the position of the two group of animals on the phylogenetic tree, their similarity with regards to maintaining body temperature is due to the fact that their evolution involves a more recent ancestor compared with the other vertebrates.

As organisms evolve beginning from invertebrates through to vertebrates, the body system becomes more complex and as they evolve within the vertebrate group.

Some vertebrates like reptiles and amphibians that were  dependent on the environment to regulate their temperature while others like birds and mammals forms complex system that enable them live on land and regulate their temperature independent of the environment.
