The early synapsids are sometimes called “mammal-like reptiles” because they look so reptile-like but have many features in the skull and teeth that reveal their close connection to mammals. Transitions of reptiles to mammals a long long time ago, in a galaxy not too far away, was a little blue planet called earth, and on this world not a single mammal lived.
Mammal to reptile evolution according to my book, the theory is that reptiles eventually evolved into mammals however, reptiles have several bones in the jaw, whereas mammals only have one. In the past, scientists might have said that early synapsids shared more features in common with reptiles than with mammals, but really we need to look at it as being more about which group is .

As mentioned above, the standard phylogenetic tree indicates that mammals gradually evolved from a reptile-like ancestor, and that transitional species must have existed which were morphologically intermediate between reptiles and mammals - even though none are found living today.

From my reading of it reptiles have been greater comfortable to floor vibrations, and did no longer pay attention the better frequencies that mammals do and that they talk in those articles a pair of transition fossil (additionally below) there is likewise a wiki point out of the genes to blame for the formation of those bones (see below . They look for “mammal-like” characteristics in different reptile fossils, hoping to find a smooth transition of reptiles becoming more “mammal-like” over time there are a number of interesting problems with this idea, two of which are 1) mosaic creatures, and 2) reversing characteristics. If it is infact a transition between mammals and birds it should place well in the known fossil record of mammals and birds but it doesnt mammals and birds have long been known to have derived from different groups of reptiles, mammals from therapsids and birds from much later therapod dinosaurs.
