Evolution

Animals move to find food, water, shelter, mates, and to avoid predators. Plants move in response to environmental cues such as sunlight (for photosynthesis), gravity (for root growth), and mechanical stimuli (e.g. touch-sensitive plants).

The emergence of two sexes likely occurred through a process called sexual differentiation, where genetic and developmental mechanisms led to the evolution of distinct male and female reproductive systems in organisms. This differentiation provided advantages for reproduction, genetic diversity, and adaptation to changing environments, ultimately promoting the survival and diversity of species.

Yes. Evolution is a fact and the theory of evolution by natural selection explains this fact.

Creationism and Intelligent Design are always rejected as science in US courts. It gives rise to a constitutional issue.

Evolutionary theory is the backbone of biology and you are not specifically educated in biology if you do not know this theory. And I would say you are not generally educated if you do not have exposure to this, one of the core theories of science.

Evolution is a slow, slow process which enacts itself over many generations. Species evolve to adapt to environments and to survive, which makes evolution the mechanism through which "survival of the fittest" succeeds as a natural order.

A couple of fads from 1971 are disco music, and cassette tapes. Acupuncture also was a fad after President Nixon found it on a trip to China. Popular foods of 1971 were Hamburger Helper and Quiches.

Protein synthesis on the primordial Earth may have been catalyzed by RNA before the evolution of enzymes. This hypothesis, known as the RNA world hypothesis, suggests that RNA molecules could have functioned both as genetic material and as catalysts for biochemical reactions, including protein synthesis.

An evolutionary track is a representation of the path taken by a population or species over time as it evolves. It typically shows changes in traits, genetic makeup, and adaptations in response to environmental pressures. By studying evolutionary tracks, scientists can better understand how species have evolved and diversified over millions of years.

There are countless examples of this type of evolution, but I will give you one; Humming birds and the elongated pouches of the flowers they eat from; If the flower already has a long pouch, and a bird who's diet is of nectar but doesn't have a long beak, birds with longer beaks will get to eat more, thus it will be healthier and get to pass it's genes on. While the flowers that don't attract as many humming birds (maybe they don't have sweeter nectar or a more attractive color) don't get polinated as much, and so they don't pass as many genes on than the ones who do.

Change of organisms over an extended period of time is known as evolution. Evolution is the process by which populations of organisms change over generations through genetic variation, natural selection, and other mechanisms, leading to the emergence of new species and the diversity of life on Earth.

Charles Darwin first published his theory of evolution through natural selection in his book "On the Origin of Species" in 1859. However, he started developing his ideas on evolution during his voyage on the HMS Beagle in the 1830s.

If perfect pitch is dominant you could have this.

PP X pp

Then all of the children will have perfect pitch.

If perfect pitch is recessive, then;

pp X Pp

then there is only a 50% chance of any one child having perfect pitch.

In the future be more precise.

Phenol is used in DNA extraction to separate DNA from proteins and other contaminants. It denatures proteins and disrupts cell membranes, allowing DNA to be separated and purified. The phenol acts as an organic solvent to extract DNA from aqueous solutions.

Charophyta; Specifically stoneworts are within a green alga lineage that million of years ago gave rise to the land plants. They have a distinctive form and sex organs like land plants. -Cengage Learning

Abiogenesis is a term used to describe two similar but notably separate ideas in science. They involve the basic principle that life can form spontaneously from nonlife.

The earliest version of this, normally refered to as 'spontaneous generation', was held by many philosophers and scientists for millenia; it is the mistaken idea that life such as maggots can arise from dead matter, that aphids grew from the dew on plants or that mice grew from hay.

Fortunately Louis Pasteur, through the use of proper scientific method, showed this idea to be incorrect. Pasteur's Law of Biogenesis simply described states that "life only comes from life not non-life" and applies to the maggots, the mice, the aphids, mammals, insects, bacteria, ... In short, everything currently living on the planet came from something else living on the planet.

The second idea is that now solely referred to by abiogenesis. It involves the process of chemical compounds in a 'primordial soup' becoming able to replicate, and then metabolise other compounds. Several hypotheses of this sort are currently being studied; experiments like the Miller-Urey synthesis have shown in the right conditions, and especially in those which are currently thought to be like that of early Earth, the basics of life can develop on their own in a very short space of time. However, the Miller Urey synthesis has many critics and it is far from having produced life, especially as complex as a "simple cell." That is also why some atheist scientists (such as R. Dawkins) suggest that life might have come from outer space...

It adjusts the position of the lenses so that the object can be seen clearly; can be coarse or fine.

In 1975, Gary Dahl introduced America to the Pet Rock. While the fad only lasted about six months, it was successful enough to make Dahl a millionaire.

'Essential' requires a statement of purpose. If an organism 'wants' as many as possible of its genes preserved in the gene pool, then replication is just what the doctor ordered. But does the cosmos care whether a lineage persists? Probably not. So in that sense, it is not essential that organisms reproduce.

The statement "organisms that are better adapted to their environment are more likely to survive and reproduce" best illustrates Darwin's theory of natural selection. This concept highlights the idea that individuals with advantageous traits are more likely to pass on their genes to the next generation, leading to the gradual evolution of populations over time.

Evolution works great, but is a slow, time consuming process. Look at how many hundreds of millions of years it took evolution to get to us. We can speed things up through genetic engineering. First, we should fix the GULO gene. It is nonsense having a malfunctioning gene for ascorbic acid synthesis. Then we could improve people so their diets could incorporate a wider variety. Genetically enhance eyesight, and other things. There are lots of things we could change, to make better people. I myself would like to be a whole lot smarter.
