Did we inherited autism through the Neanderthal and Denisovan genomes?

possibly - 

but that doesnt explain autism believed to be created by spontaneous mutations ie not inherited

I do entertain the idea, that if you have a neanderthal man who because of his biological differences would perhaps processes things differently like an autistic person perhaps, and when let's say the Neanderthal mates with a homosapien

The child would be a mix therfore a spectrum is created?

I am not saying this is the case but I would think further into it, to see if it could make sense enough to be a possibility. 

What do you think Aidie. 

i think that would be one of the biggest research projects of all time!

i recommend you read the following book written by the queen of autism Temple Grandin

https://www.amazon.co.uk/Autistic-Brain-Temple-Grandin/dp/1846044499/ref=sr_1_1?crid=UJIX1H92M3XD&keywords=the+autistic+brain&qid=1576412576&sprefix=the+autistic%2Caps%2C148&sr=8-1

she covers the genes involved in autism quite well. Also, her book is simple a good read and delivers a different attitude to autism

BTW I got it from my local library :)

ask your mum and dad if you have any Nearderthals in your family tree !

I do feel like there is some merit to the idea everytime I look into it I feel more that its a possibility. 

I think how cool would it be to have such ancient DNA be so prominent in me?

I often too wondered if memories in some part are stored in DNA and that one day we could see through our ancestors eyes. 

Wonderful concept I think, in this world there is an abundance of variety that makes anything possible.
