Evolution

Lamarck proposed that by selective use and disuse of organs, organisms acquired or lost certain traits during their lifetime. These traits could then be passed on to their offspring. Over time, this led to a change in species

If it evolution via natural selection then it is the natural that selects what traits should be passed on, for example having leg is better land animals then organisms that have leg will survive and ones that don't will die, this is natural selection, of course this happens over a long period of time. Evolution via artificial selection is where human selects the animal, perhaps the mutation may be eliminated in the wild but we think that it is suitable for our life so we mass produce the organism with that desirable trait. Like peas, ancient peas have to explode out of their pods to spread seeds but that is not good for us but then maybe one day a mutation occured and the pea pod will not explode, then we take it and breed many of that.

Wilhemina is not a scam, I am a Wilhemina model and have booked many jobs. They will not sign you if they do not think that they will be able to get you jobs..if you want to be signed with someone and not book jobs go to Carolina Talent.

In the chaparral ecosystem, pioneer species like wildflowers, grasses, and shrubs such as chamise and ceanothus are common. These plants are typically the first to establish and can thrive in the harsh conditions of the chaparral, helping to stabilize the soil and pave the way for other plant species to colonize the area.

At the demise of the non-bird dinosaurs the extant mammals were all pretty much the same, all shrew like and having four paws with five figits. as the mammal radiated into the niches that were abandoned by the dinosaurs the basic tetrapod plan remained, but the digits especially changed, Look to the variance between the paws of a tiger, retractable claws that are razor sharp, pads on the bottom for running and the five digits, Then there is the horse, hardened hoof which is the middle digit extended and the nail grown and hardened. You can now think of many differences to forelimbs in mammals engendered by their adaptive radiation. ( whales come to mind )

No, his concept of uniformitarianism posited that the same process that we see happening on the earth today were the process that shaped our world over the long eons of time since the forming of the earth

Differences between gorillas and humans are primarily due to genetic variations. Humans have a more complex brain structure, advanced language capabilities, and a greater range of physical dexterity compared to gorillas. These differences have evolved over millions of years through natural selection and adaptations to different environments.

The hypothesis for the evolution of jaws suggests that they originated from skeletal support structures around the mouth of ancient fish. Over time, these structures were modified and strengthened through natural selection to become more efficient at capturing and manipulating food, leading to the development of jaws as we see in modern vertebrates.

Evolution does not concern the origin of the universe. Evolution is a theory concerning the origin of species--diverse biological organisms--via mechanisms of inheritance with modification.

The origin of the universe is best dealt with by the Big Bang theory.

Mutation is not a way in which natural selection affects the distributions of phenotypes. Mutations introduce new genetic variations, which can then be acted upon by natural selection to influence the distribution of phenotypes within a population.

The fossil record independently confirms the general hypothesis of common descent, and allows palaeontologists and evolutionary biologists to confirm specific proposed phylogenies as well as specific hypotheses about the evolutionary past of various lineages.

The major impact of animal removal from an area can disrupt the ecosystem by affecting food chains, leading to an imbalance in predator-prey relationships. This can result in an increase in certain species which can further impact plant populations and overall biodiversity. It can also lead to changes in habitat structure and function.

Sporoderm stratification refers to the layering of the sporoderm, which is the outer layer of a pollen grain or spore. This stratification can consist of different layers with distinct compositions and functions, such as protecting the genetic material inside the pollen grain or aiding in dispersal. The structure and composition of sporoderm layers can vary among different plant species.

Jean Baptiste Lamarck's idea of the inheritance of acquired characteristics, although mostly rejected today, was one of the first systematic explanations for evolution, influencing Darwin's thinking. While Darwin's theory of natural selection differed significantly from Lamarck's, Lamarck's work helped pave the way for questioning and exploring evolutionary mechanisms that ultimately led to Darwin's own theory of evolution by natural selection.

Alfred Russel Wallace is credited as the co-discoverer of the theory of natural selection alongside Charles Darwin. Wallace independently formulated the theory while working in Southeast Asia, sending his findings to Darwin in 1858, prompting the publication of the joint paper "On the Tendency of Species to Form Varieties" in 1858.

Predator-prey coevolution is often described as an arms race because it involves a continuous cycle of adaptation and counter-adaptation between predators and prey. As prey evolve defense mechanisms to avoid being caught, predators respond by developing more effective hunting strategies or abilities. This results in a never-ending cycle of evolutionary changes as each species tries to outwit the other.

No! The eye of the octopus is a highly adaptive trait and better than the human eye because the nerves that go to the brain are not in the way of the retina as is the case in humans, A vestigial trait us a trait that is not used for it original purpose, such as the tail bone in humans.

Jean-Baptiste Lamarck is known for his theory of inheritance of acquired traits, which proposed that characteristics acquired during an organism's lifetime could be passed down to its offspring. He also suggested that organisms evolve through a process of gradual adaptation to their environment. These ideas have been largely discredited by modern understanding of genetics and natural selection.

Technically, fossils are not required to demonstrate the accuracy of the central hypotheses of evolutionary theory. The accuracy of common descent and natural selection can be demonstrated effectively only referring to observations in zoology, molecular and developmental biology, genetics and comparative genomics. However, the fossil record does allow palaeontologists to have a more detailed look at the form and behaviour of past lifeforms, something that comparative genomics by itself may not, and to confirm specific hypotheses about the nature and timing of specific events in the evolutionary history of diverging lineages. In this last category, transitional fossils are perhaps the most significant markers in the fossil record.

Jean-Baptiste Lamarck believed in the theory of inheritance of acquired characteristics, which proposed that organisms could pass on traits that they acquired during their lifetime to their offspring. He also believed in the idea of evolution, suggesting that organisms change over time in response to their environment. However, Lamarck's ideas have been largely discredited in favor of Charles Darwin's theory of natural selection.

The change over time that is the definition of evolution is quite well illustrated in the fossil record, especially at the level of higher taxa. The simplicity that becomes multicelled complexity is well written into the mineralization of the fossils left behind over the millions of years.

These genes have lost there protein coding abilities and are riddled with deleterious mutations. Two points to the evolutionary theory contribution. By example. Firstly, all great apes have a vitamin C pseudogene that links humans to all other great apes showing common ancestry. Secondly, this gene is inactive in fruitavores ( humans are common ancestors to fruitavores ) as they eat all the vitamin C they need so this gene became invisible to natural selection and deleterious mutation accumulating in the gene were not selected against as the survival and reproductive success of these organisms was no longer affected by not synthesizing vitamin C.

Generally when a species splits into two populations that are separated by some means that keeps the now individual gen pools from intermingling. This allows new alleles to arise in the separate populations and as time passes this frequency changes in alleles can give rise to new species.

The evolutionary history of primates is based on fossil evidence, molecular studies, and comparative anatomy. Fossil records show the gradual development of primate characteristics over time, while molecular studies help determine how closely related different primate species are. Comparative anatomy helps identify shared characteristics across different primate species and their common ancestors.

Reptiles evolved some 320 million years ago from amniote ancestors, specifically from advanced reptiliomorph labyrinthodons. They were among the first vertebrates to successfully sever their ancestral tie to water, as they developed impermeable skin and a mode of reproduction that did not depend upon a body of water (internal fertilization coupled with the amnion, a semi-permeable membrane that protects the embryo in the egg and allows for an exchange of gases such as oxygen and carbon dioxide, allow the developing animal to breathe).
