okay let's talk about differences
between protostomes and deuterostomes
now protostomes the mouth develops
first and I like to say see this as "pro"
and in deuterostomes the mouth develops
second and I like to see that as "do" so
do is like you know deuces it's two and
protostome is one so we can say the
mouth develops first mouth develop
second so if the mouth develops first
the second thing to develop in
protostomes would be the anus and what
are we talking about when we're talking
about developing we're talking about
this blastopore here does this
develop first into the and become the
anus or does this become the mouth in
protostomes this will be the mouth in
deuterostomes this will be the anus
