All vertebrate embryos show some similarities at an early stage. Mention two such similarities. What do they indicate?explain
Dear student.
There are many similarities that all vertebrate show at an early stage that are:
i. Presence of notochord
ii. Presence of gill arches
iii. Presence of spinal cord
All these similarities show that all vertebrate have originated from a sinlge ancestor. It is very well known fact that is proven by many scientist that all oragnism have evolved from a single nacestor and during the course of evolution , speciation took place that lead to the formation of many species.
Regards
