The theory of evolution is a big lie.

Modern science has no examples of improving of the genetic code for this reason, it is impossible to call the theory of evolution proven, but rather it can be called anti-scientific.

The point is that God created living creatures by families or as translated in the Bible after its kind.

Genesis 1:21 And God created great whales, and every living creature that moveth, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind: and God saw that it was good.
22 And God blessed them, saying, Be fruitful, and multiply, and fill the waters in the seas, and let fowl multiply in the earth.
23 And the evening and the morning were the fifth day.
24 And God said, Let the earth bring forth the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind: and it was so.
25 And God made the beast of the earth after his kind, and cattle after their kind, and every thing that creepeth upon the earth after his kind: and God saw that it was good.

God created all living beings in families (kinds) and from the beginning laid for each family all the gene base information within which the species can undergo transformation.

So the basic genetic information within which the species can undergo transformation was loaded by God from the beginning in the first individuals of representatives of each family and when the multiplication process was launched this information began to manifest itself in descendants in various combinations. Evolution does not exist and there is only a process of disclosing the information that was originally available. God originally planned to provide diversity within each family of living beings and He in His wisdom provided the ability of each family to adapt to changing external habitat conditions because He knew that the external environment would change and the animals would have to adapt to different living conditions.

The Balaam teaching and the deeds of the Nicolaitans, or the abomination which was applyed to the church.

In the book of Revelation we read about two churches, the church in Ephesus and the church in Pergamum, and both of these churches were struck by the teaching and the deeds of the Nicolaitans, and God says that He hates this teaching.

Revelation 2:14 But I have a few things against thee, because thou hast there them that hold the doctrine of Balaam, who taught Balac to cast a stumblingblock before the children of Israel, to eat things sacrificed unto idols, and to commit fornication.
15 So hast thou also them that hold the doctrine of the Nicolaitans, which thing I hate.

In what way is this doctrine and this heresy expressed?

According to the context of the second chapter of the book of Revelation, the teaching of the Nicolaitans is directly connected with the teaching of Balaam and if we find out what the doctrine of Balaam is, we will understand what the doctrine and deeds of the Nicolaitans are.
