Thus the genetic basis to the origin of bird species is to be sought in the inheritance of adult traits that are subject to natural and sexual selection.

Freud's view is that all love is sexual in its origin or its basis. Even those loves which do not appear to be sexual or erotic have a sexual root or core. They are all sublimations of the sexual instinct.

From Tree To Web
A Quixotic Quest
“The tree of life is a record of how every species that
ever lived is related to all others back to the origin of life.”
For a period of 150 years
biology sought the holy grail
of the tree of life – today
the tree has become obsolete
through negative evidence
Discovery of DNA structure led to
molecular evolution studying inheritance
as contained in the history of DNA sequences
finding species swapped genetic material
with each other, hybridising - thus the tree-
theory degenerates into impenetrable
thickets of interrelatedness
Bacteria and archaea swap
genetic material with other species
across huge taxonomic distances
in horizontal gene transfer (HGT)
Darwin assumed 'vertical' descent
but when genes were sequenced -
DNA replication and protein synthesis
showed the promiscuous exchange
of genetic information across
diverse groups

Into God Worship
You shall not pernit a false teacher to seduce you or,
Pull you away into God Worship! !
And stay away from the genetic engineering which involves the mixing of two species,
For, they are all part of Satan's work to elude many into her fold.
Par, stat, tar, car, far, bar, gar, jar, oar, war!
Spies,
Species,
Alone once again! !
And, back to square one;
But, stay away from the genetic engineering which involves the mixing of two species!
And, live like the muse of love in the land of your joy.

Owing to this struggle for life, any variation, however slight and from whatever cause proceeding, if it be in any degree profitable to an individual of any species, in its infinitely complex relations to other organic beings and to external nature, will tend to the preservation of that individual, and will generally be inherited by its offspring. The offspring, also, will thus have a better chance of surviving, for, of the many individuals of any species which are periodically born, but a small number can survive. I have called this principle, by which each slight variation, if useful, is preserved, by the term of Natural Selection, in order to mark its relation to man's power of selection.

It is essential for genetic material to be able to make exact copies of itself; otherwise growth would produce disorder, life could not originate, and favourable forms would not be perpetuated by natural selection.

Historians will have to face the fact that natural selection determined the evolution of cultures in the same manner as it did that of species.

The one process now going on that will take millions of years to correct is the loss of genetic and species diversity by the destruction of natural habitats. This is the folly our descendants are least likely to forgive us.

Animals can adapt to problems and make inventions, but often no faster than natural selection can do its work - the world acts as its own simulator in the case of natural selection.

Since natural selection requires a function to select, an irreducibly complex biological system, if there is such a thing, would have to arise as an integrated unit for natural selection to have anything to act on.

Voilates The Bond
Sexual abuse violates the bond of trust and respect,
So be wise and let us live in a peaceful world;
For negative character traits define who you are,
Just as psotive traits! !

Simplistic Solutions: Forgiveness
Forgiveness is

(hopefully) well
adjusted balanced
strong in principles
(ethics resolutions virtues)
all other character traits
as applicable.
To love again
an innocent
(man or woman)

when appropriate
to acknowledge selection
(the appeasement of taste)
is a natural

Men & Women, Women & Men
Why are women forced to be submissive towards men?
Is it true that men are the more dominant species of human?
I think not
As it is women who have been portrayed as this
By no other than the male species
We are equal
Each possessing different qualities
And both species intertwining each others traits
But there are those few how still believe
That women are inferior to men
To those few I simply say…
Women and men
The differences between us are on the outside only
People do not really talk the way they used to
But they still think that way
We have the same mind
Our spirits are different
Yet somehow they are all still connected
We breathe the same air
And walk the same path
We are alike
We just need to see it
Men & women, women & men.

Statutory warning
Bird is the subject
And you all present
To speak something
And you do not want
To speak a lie
On bird
Discussion open.
Satutory warning
From the very begining
And one who involved
Know what to do
With this subject
And all move forward.
The tree that is there
And the bird is on the tree
And the bird is on the sky
Sketch the bird at the same time
And closed the discussion
That is on.

In the beginning of the human race there was no genetic load which would cause undesirable traits such as appear in offspring of marriages between relatives today.

U-Turn
Whom
He has endowed with traits
Haven't they betrayed his faith
Gave her the state
To recreate the race
Wickedly
Flaunts those traits
In the material race
Head on
Clashes with natural process
Thus ensures
Her lead in the mad rush
Objectives divine which she was to serve
No more than a commodity in lurch.

I find the subject of childhood fascinating. I explored this subject in Speak to me of love and I am curious about portraying the often painful transition into the adult world.

Baby vs Adult
Baby is dumb
Adult has wisdom
Babies are small and crawl
Adults are tall and fall
Baby demands
Adult commands
Baby yearns to walk
Adult learns to work
Baby weeps
Adult sleeps
You carry a baby
You marry an adult
Baby chokes
Adult smokes
Baby stays at home to play
Adult brings home the pay
Baby cries
Adult sighs
Baby spikes milk
Adults like silk
And I saved this for the last
Baby at birth
Adult at death
Baby vs Adult becomes a thing of the past

To pass to the deluge, and beyond it, and to come to close quarters with our proper division, the origin of Romance itself is a very debatable subject, or rather it is a subject which the wiser mind will hardly care to debate much.

With the advent of genetic engineering the time required for the evolution of new species may literally collapse.
Sex is... perfectly natural. It's something that's pleasurable. It's enjoyable and it enhances a relationship. So why don't we learn as much as we can about it and become comfortable with ourselves as sexual human beings because we are all sexual?
