Embryonic development is the initial stage in organism's  life. Many animal and birds species shows similar embryonic growth. This indicates that they are evolved from a common ancestor. Differences in features and structures in adulthood is because of genetic information present in the embryo and the process of subsequent adaptations for the purpose of evolution.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
