The answer is similar ecological opportunities on different continents have produced some striking examples of convergent evolution.
When the Pangea continent broke apart, different continents bore varying climates hence species adapted to their environment. Convergent evolution occurred when different species gained similar anatomical features that are resourceful in the environment (continent) in which they are living. An example of convergent evolution is exhibited in bats that are mammals but have features analogous to those of birds such as wings.

• Genes can contain more than one polyadenylation site, which alters the 3' of the mRNA transcript and the inclusion/exclusion of exons.
• mRNA transcripts from the same gene can be differentially spliced to include/exclude exons.
Open-mindedness is needed for the emerging scientific ideas to be accepted (or : to not be rejected without consideration).
Additionally, open-mindedness as a attitude often leads to new scientific ideas emerging: it means that people are more comfortable to try out new things and to test new hypotheses.
