Does intelligent design challenge the theory of evolution?

The theory of evolution canNOT be called 'scientific', since 'science' is simply knowledge gained by observation and consistency in results. Therefore, Evolution as a 'scientific theory' does not qualify by very definition..

Conversely, Intelligent Design is precisely 'scientific' and is, in fact, NECESSARY and PREDICTABLE for consistent order and functionality.

For example, you may not ever 'see or know' who designed your socks, but you know they exist, BECAUSE of what they INTELLIGENTLY DESIGNED for you to wear.

Furthermore, if things as minor as the shape and size of the socks we wear must be intelligently designed for them to function as they ought to, then HOW MUCH MORE OBVIOUS must it be that complex earthly creations like oceans and lakes that provide water, or trees and plants that clean our air, provide shade, and food for humans and animals alike?

Not to mention sunlight, soil, agricultural insects, bees etc etc.

These must all be working in unison for us to exist today, and simply guessing that throwing a billion dice a billion times would create such variety and harmony is NOT—I repeat—NOT a good scientific theory, but a foolish guess that could never be tested or observed in a billion, billion years (pun intended).

So when can an observable theory become a scientific FACT? When we observe it being consistently repeated in minor details around us. Such as when we look outside our window—the magnificent order and beauty of nature, as in Autumn, the way the trees go back to sleep, protected from dying just to get ready to feed on CO2 and clean our air again next year!

Or, how we could not even be reading this comment without some unknown 'intelligent mind having designed' this very screen for a purpose—our looking into it to gather important information about our existence!

Now, our computer, which cant repair itself or protect itself like a simple tree can in wintertime, was intelligently designed and did not, and could not, create itself! (Neither even did the all-intelligent AI tech used frequently here. Yes, it was also intelligently designed)

Ultimately, if it took Intelligent Design to create AI, or your computer, or even your specific pairs of size 10 socks that rip and fall apart by themselves, then WHAT LEVEL OF INTELLIGENCE must it have taken to make something like trees that repair themselves and are reborn every year by themselves, or a complex but uniform eco system that works so perfectly it can (without the aid of mankind) balance and repair itself using every tool it has at its disposal?

A Godlike level of Intelligence, that's what.

What is the mechanism for most evolutionary change?

Most evolutionary change occurs through natural selection, where individuals with traits that provide an advantage in their environment are more likely to survive and reproduce, passing those advantageous traits on to future generations. This process leads to the gradual accumulation of beneficial traits in a population over time.

How do stars change over time and what factors contribute to their evolution?

Stars change over time due to the nuclear fusion reactions happening in their cores. As a star ages, it goes through different stages based on its mass. Factors like mass, temperature, and composition contribute to a star's evolution. These factors determine how long a star will live and what it will become at the end of its life cycle.

How does the star movement over time affect the formation and evolution of galaxies?

The movement of stars over time influences the formation and evolution of galaxies by shaping their structure and dynamics. As stars orbit within galaxies, their gravitational interactions can lead to the merging of galaxies, the formation of new stars, and the redistribution of gas and dust. This ongoing process of star movement plays a crucial role in shaping the overall appearance and behavior of galaxies throughout their lifespan.

What is an evolutionary track and how does it influence the development of species over time?

An evolutionary track is the path that a species follows over time as it adapts to its environment and changes genetically. It influences the development of species by determining which traits are favored and passed on to future generations, leading to the evolution of new species or variations within a species.

What is one basic trend in animal evoulution?

One basic trend in animal evolution is increasing complexity, with species developing more specialized structures and functions over time. This can be seen in the gradual development of anatomical and physiological adaptations in response to changing environments and ecological pressures.

Darwin concluded that organisms on the Galápagos Islands?

Darwin concluded that organisms on the Galápagos Islands showed variation from island to island, leading to his theory of natural selection as a mechanism for evolution. He observed unique adaptations in species such as finches and tortoises, which helped support his ideas on how species could change over time in response to their environment.

What is cuvier theory of evolution?

Cuvier did not propose a theory of evolution; he was a proponent of catastrophism, which suggested that the Earth's geological features were mainly shaped by sudden and short-lived events like natural disasters. Cuvier believed that different catastrophes caused the extinction of species, and new species were created following each event. His ideas contrasted with those of proponents of uniformitarianism, like James Hutton and Charles Lyell, who argued that slow and gradual processes shaped the Earth's features over long periods of time.

Are seals and dolphins examples of convergent evolution?

Yes, seals and dolphins are examples of convergent evolution. Despite having different ancestors, they have evolved similar streamlined body shapes, flippers, and adaptations for swimming in their aquatic environments. This convergence is a result of facing similar environmental pressures in their habitats.

Who believed if an individual uses a trait more it gets bigger lamark or Darwin?

Jean-Baptiste Lamarck believed that if an individual uses a trait more frequently, it will become more developed and prominent in subsequent generations. Charles Darwin, on the other hand, proposed that favorable traits are naturally selected for in a population over time through the process of natural selection.

How do the people affect the Earth?

People affect the Earth through activities like deforestation, burning fossil fuels, and producing large amounts of waste, which contribute to climate change, habitat destruction, and pollution. Human actions can alter ecosystems, disrupt natural processes, and lead to negative consequences for the environment. Ultimately, human impact plays a significant role in shaping the health and future of the planet.

Why whites are white and blacks black?

The color differences in human skin are due to the presence of melanin, a pigment produced by specialized cells called melanocytes in the skin. People with darker skin produce more melanin, which helps protect against harmful UV radiation. People with lighter skin produce less melanin, resulting in lighter skin tones. The differences in skin color have evolved over time in response to different levels of UV radiation in various regions of the world.

Which event in the cell cycle is DNA duplicated?

DNA duplication occurs during the S phase of the cell cycle. This is when the DNA is replicated to ensure that each daughter cell receives a complete set of genetic information.

Who figured out evolution?

Charles Darwin is credited with developing the theory of evolution through natural selection in the mid-19th century. His groundbreaking work laid the foundation for our modern understanding of how species change over time in response to their environments.

Are humans made by God or evolved from monkeys?

Humans have evolved over millions of years from ancestral primates, not directly from monkeys. The theory of evolution explains how species, including humans, have changed and adapted over time through natural selection and genetic variation. This scientific understanding is separate from religious beliefs about creation.

What evolutionary advancement does the operculum provide?

The operculum assists in protecting the gills of fish and regulating water flow for respiration. This evolutionary adaptation allows for better oxygen exchange and helps prevent debris or predators from entering the gills.

When did crocodiles first appear?

Crocodiles first appeared around 200 million years ago during the Mesozoic Era. They are ancient creatures that have remained relatively unchanged over millions of years.

What are the geographical barriers that contribute to the process of speciation or natural selection?

Geographical barriers such as mountains, oceans, rivers, and deserts can prevent gene flow among populations, leading to reproductive isolation and eventually speciation. These barriers create isolated environments where different selective pressures can act, driving the evolution of distinct traits in separated populations. Over time, these differences can accumulate, resulting in new species adapted to their specific environments.

What is the explanation for the law of use and disuse?

The law of use and disuse, proposed by Jean-Baptiste Lamarck, suggests that organs in an organism's body will develop with increased use and deteriorate with disuse. This theory has been largely discredited in evolutionary biology, as traits are now understood to be inherited through genetic information rather than acquired through individual actions during an organism's lifetime.

What species have evolved due to geographic isolation?

Some examples of species that have evolved due to geographic isolation include the Galapagos finches, Hawaiian honeycreepers, and the marsupials of Australia. Geographic isolation can lead to the development of distinct traits and adaptations in isolated populations over time, eventually creating new species.

Describe three holes in Darwins theory?

First of all, the fossil record does not support the theory of evolution. The fossil record shows that species abruptly appear and disappear, almost as if they were created. There is absolutely no evidence in the fossil record of species gradually changing into different species. Darwin himself said that these revelations in the fossil record could be used as the most compelling arguments against his theory.

Secondly, in order for Darwin's theory to be plausible, it needs vast amounts of time (thus, evolutionists claim that earth is millions and millions of year old). But for the earth to be old enough to accommodate Darwin's theory would be impossible. The intensity of the electromagnetic sphere around the earth steadily and consistently decreases by seven percent about every one hundred years. When we look back in time and calculate the intensity of the electromagnetic sphere by adding seven percent every hundred years, we find that the electromagnetic sphere was so intense just twenty thousand years ago, that it would have literally dissolved the core of the earth. How then can the earth be billions of year old?

Thirdly, Darwin made his theory in the 1800s. Science has grown by leaps and bounds since then. Here is an example: Genetics was not developed as a science in Darwin's day, and he assumed that animals essentially had an unlimited capacity to adapt to environments -- unaware that no change could ever take place without the right genes being there. To resolve this dilemma, modern evolutionists asserted that the fish's genes must have mutated into human genes over eons. Mutations, of course, are abrupt alterations in genes. However, this hypothesis is no longer tenable. Dr. Lee Spetner, who taught information theory for a decade at Johns Hopkins University and the Weizman Institute, spent years studying mutations on a molecular level. He has written an important new book, "Not by Chance: Shattering the Modern Theory of Evolution" In it, he writes, "In all the reading I've done in the life-sciences literature, I've never found a mutation that added information. ... All point mutations that have been studied on the molecular level turn out to reduce the genetic information and not increase it."

Is sleeping an inherited behavior?

Sleeping patterns can be influenced by genetics, but the act of sleeping itself is a basic physiological need for all humans. However, the amount of sleep needed and the timing of sleep can be partly inherited. Factors such as circadian rhythms and sleep disorders can also play a role in one's sleep behavior.

How has the theory of evolution affected the science of taxonomy?

The theory of evolution has influenced taxonomy by providing a framework to understand and classify species based on their evolutionary relationships. Taxonomists now use evolutionary principles to group organisms into categories that reflect their common ancestry, leading to a more systematic and comprehensive classification system. This has helped improve our understanding of biodiversity and the relationships between different species.

How can a bats wing be considered a homologous structure and an analogous?

They are homologous in the sense that all tetrapods share that forelimb structure. They are analogous because both bats and birds adapted flight to their local environmental conditions. One being a mammal, that has the finger extension type wing and one being aves with the full forelimb extending the wing. They have the flight in common, but not the structures, so are analogous. They have an ancestral condition leading to the similarity of forelimb structure and so are homologous.

How tree of life explains both unity and diversity of life?

The tree of life concept illustrates unity by showing that all living organisms share a common ancestry, with the trunk representing this shared origin. The branches and twigs demonstrate diversity as different species have evolved and diversified over time. This visual representation helps us understand the interconnectedness of all living things while highlighting the variations that have occurred through evolution.
