"The juvenile sea squirt wanders
through the sea searching for a suitable rock or hunk of coral to cling to and
make its home for life. For this task, it has a rudimentary nervous system.
When it finds its spot and takes root, it doesn't need its brain anymore, so it
eats it!"

Ontogeny Recapitulates Phylogeny
Ok…I know
you’re wondering….. “What the heck?”
If you will,
give me 227 words to explain.I know we’re all pattern seeking creatures, but there is something that happens to me every time I listen to people speak, or any time I read a book. I can’t help but see words/stories in metaphors.
An example….Someone
said the other day, “we’re never there”…I immediately thought, “That’s because
we’re always here…right here…right now.”
So where am
I going with this?I’ve recently been reading about bugs and parasites. Every sentence I read brings forth a new perspective about human behavior. There are certain behaviors in other species that appear to be recapitulated (brief summary) in humans.
So this is
where the title comes from. Let’s look at the definition….
Ontogeny - The origin and development of an individual organism from embryo to
adult.
Recapitulates - To give a brief summary of something….to reiterate.
Phylogeny - the evolutionary history of a kind of organism.
( By the way, this theory has been
disproven)
The easiest
explanation for this hypothesis is that in developing from embryo to adult,
animals go through stages resembling or representing successive stages in the
evolution of their remote ancestors.I would like to share 3 stories of different species behaviors (juvenile sea squirt, moth, and parasite) that appear to be recapitulated in humans.
Thanks for
listening to my pattern seeking mind!
