Biogeography- branch of biology that deals with the geographical distribution of plants and animals. Example: The Galapagos finches is a major example of this because it proves the evolution of how earth once was and how genetic drift plays a role in evolution Artificial selection- Breeding of plants and animals to produce desirable traits. Example: Racehorses because they thoroughbred, Vestigial Structures- A structure in an organism that has lost most or all of its original function. Example: the pelvis a whale and the appendix in a human they both either serve or use to serve a purpose once
The hominid has to change to adapt to the new environment and this is a reference to Darwin's natural selection. If an animal does not adapt, they will not survive long enough to reproduce and pass on their genetic make-up. This is how evolution occurs. Frequent changes such as these cause genetic variation, mutations and
We have technology that can examine the DNA of humans and compare it to DNA from other living organisms. Darwin’s theory is that humans are the result of evolution from the ape. With the world ever developing , the theory is that the ape developed into a Neanderthal and the finally into a human. This theory may be believable, as according to Dr. Nolan in Greer’s article “Neanderthals are 99.5% genetically identical to humans, and chimps and apes are 96-97% identical” – this shows that there are similarities between humans and both Neanderthals and apes , however the majority of people disagree with this theory as they say there is too much of a difference. This is what people feel when the statistics show similarity of a minimum of 96% similar.
creationism assignmentCreationism Introduction Creationist are group of people who believe that the Creator spoke and all things came into existence and that man, plant and animals are not blood related. Evolutionist is a group of people who believe man and beast are blood related because they evolved from the same ancestor and have developed naturally. Agnostic is a group of people who believe the origins of man cannot be discovered. Creationist theories Bonnet was a naturalist one of the first man who came up with the scientific theory of creationism, his philosophy was known as emboitment.He assumed that everything was created as a germ and after ages these turn to adult which also means that things were formed from simple to complex.
The internal and external anatomy of Labeo umbratus Hannah Janse van Vuuren Abstract The anatomy of an Labeo umbratus specimen, found in the Krugersdrif dam, was studied. Annotations of the positions of the internal organs as well as the external morphological characteristics were made. Upon further analysis, several characteristics were identified that would have eased life in aquatic environments. Some of these characteristics include sensory receptors located on the head as well as on the lateral view of the body, the shape of the fish, specialised, paired appendages, respiratory structures, as well as structures aiding the fish in buoyancy. The way in which the internal organs and the external appendages were arranged in
The theory of evolution by natural selection and the evidence presented by Darwin. The evolution of biological organisms describes the changes within different populations which creates variability in their phenotypes and genotypes. The fundamental basis of evolution, is that every living individual is related by a common ancestor (Strickberger,2000.). Charles Darwin, in 1859, published one of the most credible and compelling theories of evolution, in his book ‘the origin of species’ (Darwin and Beer, 2008), which best explains the theory of natural selection. Darwin’s theory of natural selection states that living individuals show two types of variation in their phenotypes; favourable and injurious and it is the inheritance of the favourable
Scientists cannot recreate evolution, therefore, it can only be a theory and can only be trusted if a person has faith that it is true. If evolution was a true event that happened, there should be many transitional species today that scientists could study. Today scientists don’t have any live animals that are thought to be a transitional species that is going to evolve into something else. With similar species thought to come from a common ancestor, all traits of one of the species should be found in the other species in about the same area. There are many cases where two species have many things in common, but the two species also have some very distinct characteristics that are unbridgeable between the two.
Terresterial adaptations – Amphibians left water, and emerged on the land for the first time somewhere around 360 million years ago, and the fact that they continue to exist even today, while several other species. Life on land was pretty different from life in water for this species, as a result of which early amphibians had to undergo several changes and adapt to the new environment to ensure survival on the planet. *Lungs to breath air *Well developed feet that allow them to jump. *Skin is strong enough to keep them from immediately drying out in the
Both evolution and creation theories have completely have completely different ideas but they are based on the same topic, which is how our world and living beings in it were created and how they evolved. Both of the two theories are equally believable to this day, even though earlier in time there was much more information on the creation theory because science and technology were not very developed yet. Both of the theories al backed up with a ton of information right now, so it is much more easier for people to decide what they want to
The seventh avatar was of the Lord Ram (The perfect man; the king of Ayodhya) who uploads old rules at the cost of personal life. His eighth avatar was of Lord Krishna (The Divine Staesman) Cowherd/ charioteer/ stateman who shrewdly changed rules. The ninth avatar was that of Balram (Elder Brother of Krishna). One of the ten avatars of Vishnu that appeared in the Dwapara Yuga. In many versions of the mythology, the ninth incarnation is often mentioned as Lord Buddha.
