Evolution

Archebacteria obtain their energy through various metabolic pathways such as chemosynthesis, where they harness chemical energy from inorganic compounds like sulfur or iron. They can also utilize sunlight through a process called phototrophy to produce energy. Additionally, some archebacteria can derive energy from organic molecules through fermentation or respiration.

The first group of animals to have an anus were believed to be cnidarians, which include jellyfish and sea anemones. An anus allowed for the efficient removal of waste from their digestive system.

Lamarck believed that traits acquired by one individual, will be immediately passed down on it's descendants. FE: If your father was a smith, you will have stronger muscles and bigger hands. Which is not true because evolution like that happens over thousands maybe millions of years and genetic changes are only expressed if the mutations occur in the DNA of the reproductivecells (spermproducingcells etc)

Note: Lamarck has proven to be right by scientist nowadays in the point of genetic expression: Children of people who survived the Hunger Winter in Holland of 1944 have more chance on heart diseases and become thicker more easily. This change is directed to the fact that certain events can activate certain genes, thus stating that Lamarck's theory isn't entirely wrong

Lamark's Theory of evolution suggested that organisms can pass on genetic traits that were acquired through their lifetime. This is also known as the theory of inherited traits.

So what does all this mean?

I'll give you an example: Say you were born and you began working out as a teenager. By the age of 30, you developed a bulky body. Then you have a child. Lamark's theory suggest that the baby would eventually have muscular arms without going to the gym.

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.
