A population of interbreeding organism is considered the basic unit of evolution, but genes alleles would be the unit of selection. According to the national academy,
Evolution:
Evolution consists of changes in the heritable traits of
a population of organisms as successive generations replace one another. It is populations of organisms that evolve, not individual organisms.

what is an organism in this sense,? when you say population of organisms, do you know how stupid that sounds
Millions of people are taught that the fossil record furnishes proof of evolution. But, where are there fossils of half-evolved dinosaurs or other creatures?
The fossil record contains fossils of only complete and fully-formed species. There are no fossils of partially-evolved species to indicate that a gradual process of evolution ever occurred. Even among evolutionists there are diametrically different interpretations and reconstructions of the fossils used to support human evolution from a supposed ape-like ancestry.
Even if evolution takes millions and millions of years, we should still be able to see some stages of its process. But, we simply don't observe any partially-evolved fish, frogs, lizards, birds, dogs, cats among us. Every species of plant and animal is complete and fully-formed.
Another problem is how could partially-evolved plant and animal species survive over millions of years when their basic organs and tissues were still in the process of evolving? How, for example, were animals breathing, eating, and reproducing if there respiratory, digestive, and reproductive organs were still evolving?
In fact, precisely because of this problem more and more modern evolutionists are adopting a new theory known as Punctuated Equilibrium which says that plant and animal species evolved suddenly from one kind to another and that is why we don't see evidence of partially-evolved species in the fossil record. Of course, we have to accept their word on
blind faith because there is no way to prove or disprove what they are saying. These evolutionists claim that something like massive bombardment of radiation resulted in mega mutations in species which produced "instantaneous" changes from one life form to another. The nature and issue of mutations will be discussed later and the reader will see why such an argument is not viable.
The fact that animal and plant species are found fully formed and complete in the fossil record is powerful evidence (although not proof) for creation because it is evidence that they came into existence as fully formed and complete which is possible only by creation.
Evolutionists claim that the genetic and biological similarities between species is evidence of common ancestry. However, that is only one interpretation of the evidence. Another possibility is that the comparative similarities are due to a common Designer who designed similar functions for similar purposes in all the various forms of life. Neither position can be scientifically proved.
Although Darwin was partially correct by showing that natural selection occurs in nature, the problem is that natural selection itself is not a creative force. Natural selection can only work with those biological variations that are possible. The evidence from genetics supports only the possibility for horizontal evolution (i.e. varieties of dogs, cats, horses, cows, etc.) but not vertical evolution (i.e. from fish to human). Unless Nature has the ability to perform genetic engineering vertical evolution will not be possible.
The early grooves in the human embryo that appear to look like gills are really the early stages in the formation of the face, throat, and neck regions. The so-called "tailbone" is the early formation of the coccyx and spinal column which, because of the rate of growth being faster than the rest of the body during this stage, appears to look like a tail. The coccyx has already been proven to be useful in providing support for the pelvic muscles.
Modern science has shown that there are genetic limits to evolution or biological change in nature. Again, all biological variations, whether they are beneficial to survival or not, are possible only within the genetic potential and limits of a biological kind such as the varieties among dogs, cats, horses, cows, etc.
Variations across biological kinds such as humans evolving from ape-like creatures and apes, in turn, evolving from dog-like creatures and so on, as Darwinian evolutionary theory teaches, are not possible unless Nature has the capability of performing genetic engineering.
Biological variations are determined by the DNA or genetic code of species. The DNA molecule is actually a molecular string of various nucleic acids which are arranged in a sequence just like the letters in a sentence. It is this sequence in DNA that tells cells in the body how to construct various tissues and organs.
The common belief among evolutionists is that random mutations in the genetic code over time will produce entirely new sequences for new traits and characteristics which natural selection can then act upon resulting in entirely new species. Evolutionists consider mutations to be a form of natural genetic engineering.
However, the very nature of mutations precludes such a possibility. Mutations are accidental changes in the sequential structure of the genetic code caused by various random environmental forces such as radiation and toxic chemicals.
Almost all true mutations are harmful, which is what one would normally expect from accidents. Even if a good mutation occurred for every good one there will be thousands of harmful ones with the net result over time being disastrous for the species.
Most biological variations, however, are the result of new combinations of previously existing genes - not because of mutations.
Furthermore, mutations simply produce new varieties of already existing traits. For example, mutations in the gene for human hair may change the gene so that another type of human hair develops, but the mutations won't change the gene so that feathers or wings develop.
Sometimes mutations may trigger the duplication of already existing traits (i.e. an extra finger, toe, or even an entire head, even in another area of the body!). But mutations have no ability to produce entirely new traits or characteristics.
how children with different color hair (i.e., blond, brunette, brown, red ) can come from the same parents who both have black hair.
All varieties of humans carry the genes for the same basic traits, but not all humans carry every possible variation of those genes. For example, one person may be carrying several variations of the gene for eye color (i.e., brown, green, blue) , but someone else may be carrying only one variation of the gene for eye color (i.e., brown). Thus, both will have different abilities to affect the eye color of their offspring.
