What else can I help you with?
Can similar environments lead to the evolution of similar animals even if they are not close relatives?
False
How many people believe in the theory of evolution?
When the evolutionary theory was first proposed, people didn't believe it. Often, religion and evolution contradict themselves and even today, there are many people who favor creationism over evolution.
State the difference between geological evolution and organic evolution?
The word evolution has grown to be rather over-used and sometimes even misused, and is commonly used to refer to non-biological systems when talking about them in a sense of their changes over a period of time. For example, while computer systems do not evolve in the way biological organisms do, they have changed drastically over the years through a series of smaller changes. Outwardly this system appears very similar to biological evolution, and so evolution phraseology is useful in this context. Geologic evolution refers to a system of changes within a geological system. An example would be studying how a specific area has changed from ocean to mountains to desert over a period of time. Once again, geological systems do no progress in a "natural selection" sense such as true evolution, but they can change in drastic ways via a series of smaller changes over a very long period of time. Organic evolution presumably refers to a system of changes within a biological range. This could refer to the evolution of species or traits within a species, or may even relate to pre-biogenesis evolution of basic amino-acid strands.
Is evolution directional?
No, evolution is not directional as the definition is; the change in allele frequency over time in a population of organisms. Google barnacle to see that evolution has no particular direction, but the adaption of the organism to the immediate environment.
Why evolution of man considered as a complex process?
The evolution of man is considered a complex process because it takes thousands of years for even a small change to occur. It is a result of genetics and physiological changes which take many generations to take hold.
What are some examples of divergent evolution?
All reproductively isolated populations diverge genetically. Even in cases where convergent evolution occurs, this is only at the behavioural and morphological level. At the molecular and the genetic level, even these instances still diverge at the genetic level.
Does evolution often proceed at different rates for different organisms?
Yes. There is no set rate for evolution; the speed by which populations diverge behaviourally, morphologically and genetically is determined entirely by circumstance. Even different genes in the same population gene pool can have different rates of evolution.
Does evolution happen when species are ready?
I'm not sure I understand the question. It presupposes that there is some state of "non-readiness" in which lifeforms can find themselves. But all species are "fully-formed", even transitional forms. Evolution and speciation are continuous processes; they do not proceed from one stage to the next.
Is evolution over?
No, evolution is not over. Whenever the environment changes, and it is changing all the time, life has to adapt. Even without environmental change, slow, gradual honing of species to their niches would continue, and there is also the matter of genetic drift.
Can evolution be measured?
Yes, evolution can be measured through changes in traits, genes, or populations over time. This can be done through comparative studies, genetic analysis, or observing how species adapt to their environment.
Are technology and human evolution symbiotic or independent?
If you're referring to genetic evolution through natural selection, it's far too slow to have been affected by technology, or even civilization. However, technology affects every aspect of human life, so even natural selection will be greatly affected by it given a large enough timescale.

Why identical parents produce unidentical offsprings?
Identical parents can produce unidentical offspring due to genetic recombination and mutation during the formation of gametes (sperm and egg). Even with identical genetic material, random assortment of chromosomes and environmental factors can influence traits. Additionally, epigenetic factors and gene expression can vary, leading to differences in phenotypes among siblings. Thus, the combination of genetic variability and environmental influences results in unique offspring.
What are the major laws in evolution?
Answer 1As there is only one law of evolution, which is the natural " Law of evolution". All others are false. The Law of evolution is the naural changes in all things through better eating, living conditions, better health care and so on. The "Law of evolution" has been going on since our first parents. The "Theory of evolution" is according to mans own ides.Answer 2There are a number of "laws of evolution", although I could not tell you whether they are "major" or not. A few examples:- The law of genetic divergence of reproductively isolated populations. This states that, when the entirety of the population gene pool is assayed, one will observe divergence between reproductively separated populations. More often than not, such genetic divergence may be associated with morphological and behavioural divergence.- Evolution is irreversible. On the level of the population gene pool, this means that genetic divergence between separated populations will only increase, never decrease. On the level of the single lineage, this means that one should not expect to see a reversal of a feature to an earlier state on the genetic level: the chances are massively against such an occurrence, and decrease with every offset basepair. Note that this law specifies divergence on the genetic level: even diverging genetics may still produce convergent phenotypes.See the YouTube video linked below for a more indepth treatise on some of the laws of evolution.

Why is Darwin's theory considered incomplete?
All theories are incomplete and never proven. They are the explanations for observations, laws, facts and experimentation. They can be added to and even overturned if now information comes to light. Darwin himself had a very poor mechanism for heredity that was overturned by Mendel's genetic discoveries.
Where does human evolution lead to?
Evolution is. Evolution is not progressive, directional or linear. That prediction on where human evolution will lead cannot be made. Evolution occurs when a certain trait increases an individual's odds of reproducing at a given time. It can be something as minor as eyes set further apart or a straighter nose. It fluxes within populations even in succeeding generations.
