What is the "reptilian" part of our brain?

Question

Someone mentioned this in responding to a question about vegetarianism. Do you think we came from lizard people?

Not sure how this basic functionality leads to the conclusion that it's "reptilian"

Answer 1

They're referring to the more primitive part of the human brain, which does indeed bear considerable resemblance to the corresponding part of a reptile's brain.

Answer 2

even however is there a purpose to assume that it is so? If we initiate off conversing approximately "maybes," we are able to have faith up any end. in all likelihood there are unicorn-utilizing leprechauns that masquerade as chipmunks to realize us till the day they carry approximately their rule (they assassinated JFK because of the fact that he obtained too almost the actuality). probably there are a trillion gods, they often're rather frustrated that our backwater planet invented the cellular telephone. may be diamonds are softer than talc under particular prerequisites. may be there may be everybody who fairly can experience it somewhat is not any longer butter. the component is that we are waiting to communicate "maybes" all day long, and perhaps even have extremely of exciting in the attitude. yet, whilst the enjoying cards are down and we might desire to make a selection the form to stay our lives and what motives to do no longer overlook as genuine, then we've have been given to return to a selection what the evidence somewhat helps. the two-dimensional well being practitioner had a reason to think of that kidneys might desire to be eradicated in a ability that he won't be in a position to comprehend. can we've a purpose to assume that there is a god? As an atheist, I to find the "factors to assume he exists" to be absent. The arguments by ability of no ability save up and the evidence is lacking from understanding. The universe is religiously ambiguous, and we can not wait continuously on answering the questions on the terrific thank you to assume and act on the wager that some concerns that predicament our lives probably out of the realm of human wisdom.

Answer 3

The "reptilian" part of our brain, is the part(s) that controls basic body functions: heart pumping, lungs breathing, digestion and to a certain extent, sex, hunting food, eating.

Even the simplest life forms, like reptiles, have brains that carry on those necessary functions and not much else. Those parts of our brains, carry out those tasks, and not much else. Hence, "reptilian" brain.

Answer 4

The answer is your first answer. She should get best answer. because that's the part of our brain in all animals that control our autonomic nervous system. That which you don't tell your body to do, such as breathing, digestion, heart beat etc.

Parts of our genetic code are in trees, too. We are all connected in our DNA.

Think of all living things that have come and gone as the tree analogy. Species growing from one branch to form more branches many of them parallel to each other while some some die off forever.

Many branches are so far removed on a different part of the tree trunk that they are unrecognizable from each other. Like a crocodile and a human. Totally unrecognizable as coming from something in relation to both eons and eons ago.

There were so many different species of humans, its truly mind boggling if one wants to delve into evolution. The last known species of human we lived along side with, all died off about 174 thousand years ago. The DNA code of Neanderthals is 99% our own DNA, they extracted the DNA from the bones.

Each section of developed brain can actually be compared to each stage of intelligence to animals. What makes us different from any other species is our frontal lobes. That's the leap that created the ability to pass on complex ideas from one human to another.

When they were showing monkey brains, the larger brain had a social life of 30 of its own kind and the smaller, about 8 or 9 for its life time.

All I can say is that the process to get to where we are and where we are going is fascinating.

Answer 5

The hippocampus and cerebellum, but not the frontal lobes.

Lots of good answers here.

Mainly just the parts that keep you alive. Not the parts that are for thinking and planning and art and all that "human" stuff.

Answer 6

It refers to the survival instinct.

Answer 7

See below. No.

Answer 8

in 'our' brain, do you mean 'our' as in the 'communal' brain?
isn't it that scaly, cold blooded part?
