Sexual selection

Explaining Evolution Evolution has always been a relevant topic, whether being explained in learning environments or thoroughly investigated by scientists, why is it so important? Evolution tells the story of how humans, as well as other species, came to be. The articles “12 Examples of Evolution Today” by Erin Brodwin and “A Possible Break in One of Evolution’s Biggest Mysteries” by Peter Brannen are both compelling with the information they provide, and contain insights into the world of…

Australopithecus were approximately 35% of the span of a current human cerebrum. Most types of Australopithecus were modest and gracile, generally standing 1.2 to 1.4 m (3 ft. 11 into 4 ft. 7 in) tall. In a few varieties is an impressive level of sexual dimorphism, guys being bigger than females (“Australopithecus") The Lucy example is an early australopithecine and is dated to around 3.2 million years prior; Lucy was found in 1974 in Africa, close to the town Hader in the Awash Valley of the…

believes that we must teach general population evolution of biology. The general population is not very knowledge about evolution. These leads to problem of understating what are drugs doing to our body. Therefore, if we picking fight with natural selection and evolution we must understand evolution very…

of Darwin’s “On the Origin of Species” in 1859, natural selection has been widely accepted by the scientific community as the engine that drives evolution, or the change of frequency of heritable characteristics in a population over time. Natural selection results in the survival of the fitter individuals of a given population, and therefore the increase in frequency of the genes that produced the adaptive phenotype. For natural selection to occur, there are three conditions that must be met.…

The mechanism of evolution occurs from natural selection, where the favorable traits are preserved and the unfavorable traits are destroyed. In Revenge of the Nerds, the author Steven Pinker claims that our common ancestor had four traits that led to the evolution of the modern human, which in turn established a foundation for humankind’s intelligence. Pinker states that the four traits are vision, group living, the ability of the hand, and hunting. In support of these four reasons, Pinker…

In public schools, science-based classes focus a decent amount of time on the topic of evolution. Charles Darwin, a naturalist, and geologist is best known for his theory of evolution. Evolution is a change in the inheritable traits of biological populations over successive generations. More specifically Darwin discusses that all species of life have descended over time from common ancestors, one prime example was that humans evolved from ape-like species. Charles Darwin’s theory always had some…

survival. Charles Darwin was a man who studied evolution, and was the founder of the Natural Selection theory. Darwin’s research explored one the fundamental process, known as Natural Selection. Natural selection is the process in which those with the beneficial characteristics that increases it survival rate within a species will move on and reproduce, passing on DNA to the next generation (Natural Selection: Charles Darwin & Alfred Russel Wallace, n.d.). All the beneficial features will…

I agree with the theory of evolution because there are many evidence for it. The evidence includes fossil record, species distributions, vertebrate development process and fossil layers and so on. First, fossil is very important for understanding biological evolution. It can tell us how the living creature evolved. Second, it is species distributions. According to theory of continental drift, it found out many similar fossils even in the place oversea. Third is vertebrate development process,…

Alfred Wegener was a german scientist who developed the theory of Continental drift. He believed all the continents were one land mass. He called this super continent “Pangea”. Wegener used evidence from three sources to support his theory. First, was fossil evidence from reptiles and plants. “Cynognathus” was a reptile that had fossils found on South Africa, and Africa. This is only possible because of continental drift, the animal couldn't have swam across a whole ocean. The next reptile is…

through the Earth we all are changing. We are born and then we grow into adults and we get older and we die. A new generation is born by us dying. We are all apart of each other in some form or fashion. Charles Darwin had a theory call the natural selection. He observed that: if we all produced successfully…
