Evolution

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.

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 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.

Cuvier believed there was no evidence for the evolution of organic forms but there was evidence for succeeding creations after the catastrophic extinction events.

But in the course of history, he said, catastrophic events had killed off all members of some species, and their fossils would no longer be seen in the rocks. Later, he believed the old species were replaced by new ones that repopulated Earth.

Like many other scientists of his day, Cuvier spoke about the theory of catastrophism. This theory was based on the statement that there have been violent and sudden natural catastrophes such as great floods and other very sudden physical changes to the earth. Organisms that were living in those areas where these sudden, violent changes had occurred were often killed and replaced by new life forms moving in from other geographic areas. The fossil record of this type of area would show rapid changes in species.

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.

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.

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.

DNA is replicated in the S phase; synthesis phase.

There have been quite a few humans who tried to work out how organisms change with time. Lamarck tried his ideas but was discredited.

Today's Theory of Evolution was discovered with evidence and thought by Charles Darwin and Alfred Russel Wallace. Darwin spent the most energy on gleaning evidence so the theory is these days credited to him. As David Attenborough says, he gave the idea 'irresistable force' when he happened upon a mechanism by which it could occur: Natural Selection.

Religious believers of creation say humans are made by God.

Otherwise, neither; evolution does not teach that humans evolved from monkeys, but instead from ape-like creatures millions of years ago.

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.

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.

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.

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.

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.

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."

A BIG NO! because sleeping is... 1. 1. A natural periodic state of rest for the mind and body, in which the eyes usually close and consciousness is completely or partially lost, so that there is a decrease in bodily movement and responsiveness to external stimuli. During sleep the brain in humans and other mammals undergoes a characteristic cycle of brain-wave activity that includes intervals of dreaming. 2. A period of this form of rest. 3. A state of inactivity resembling or suggesting sleep; unconsciousness, dormancy, hibernation, or death.

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.

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.

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.

Apes are like humans in many ways, such as having similar DNA, social structures, and cognitive abilities. They also exhibit emotions, tool use, and problem-solving skills like humans. Additionally, apes share many physical characteristics with humans, such as opposable thumbs and similar facial expressions.

the theory of evolution through natural selection, as it shows how species have adapted to different environments. This distribution reflects the process of speciation and evolution, where organisms have diversified to inhabit a wide range of habitats and niches.

Humans have tail bones are are vestigial. When humans stopped using tails, over several generations, they began to shrink, and now we are left with tail bones. However, there have been cases of people who were born with vestigial tails several centimeters long.

An example of a vestigial organ is the appendix.

Two or more taxa may have shared derived traits due to a common evolutionary history, where the traits were inherited from a common ancestor. This is known as homology. Alternatively, shared derived traits may also arise independently in different lineages due to convergent evolution, where similar environmental pressures result in similar adaptations.
