Question

what are the main differences and adaptation productively between eutherian mammals and marsupial mammals? explain how homoplasy and ecotype intersect at the ordinal level?

Answer 1

There are two types of mammals marsupial mammals and eutherian mammals. The difference between them is that marsupial mammals don't contain placenta and eutherian mammals contain placenta that connects the child to the mother's uterus.

Adaptation is the evolutionary process in which the organism suited to the particular habitat and productivity is the quality of being productive. The life cycle of marsupials mammals contains peculiarities (a different feature of habitat). Marsupial mammals have the feature that it is adapts to low-productivity environments. Hence the difference in marsupial mammals and eutherian mammals is that marsupial mammals have high adaptation productively as compared to eutherian mammals.
