As animals have evolved large body size, they have also evolved adaptations to improve the exchange of energy and materials with the environment. for example, in many larger organisms, evolution has favored lungs and a digestive tract with

a. increased thickness
b. more branching or folds
c. larger cells
d. decreased blood supply

b. more branching or folds

Explanation:

Animal size has increased during evolution on several animals, this has favored enhancements in gas exchange because this enlargement made diffusion too slow to cover internal distances in an efficient time, therefore branches and foldings were developed to cover distances quicker.

I hope you fidn this information sueful and interesting! Good luck!

a community that experiences major changes undergoes progress

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.
