Sexual selection

Before one we can discuss some misconceptions about Evolution; we have to define the term first. Evolution is a process that is observed over time to see which different kinds of organisms have shown signs of development and diversified from earlier forms during the history of the earth. A few misconceptions that I have heard about evolution is one that my grandfather is always telling me; that us as humans are not letting natural take its course on us as humans, because we are always using…

1859, Darwin published his book called Origin of Species. In his book, he talked about his theory of evolution and his travels around the world discovering this phenomenon. Darwin was the first person to publish the theory of evolution by natural selection. During Darwin's educational period, he studied medicine, but he had to stop when he found out he could not handle…

guppies occur. So what causes the color variation within the Venezuelan guppies? The three factors that causes color variation within the guppies are the predatory fish residing in the pools, the amount of turbidity of the water in the pools, and the selection of mates. The amount of turbidity within the pools are one of the three factors that causes color variation within the guppies. Turbidity is the cloudiness or haziness of a fluid which is caused by a large amount of particles that are…

had an obsession with insects and bugs from a young age. • Darwin started off as a geologist, but over time he began to develop his theories and became a naturalist. • Darwin brought forward one of his main theories which was ‘Natural Selection’. • “Natural selection is Darwin’s most famous theory; it states that evolutionary change comes through the production of variation in each generation and differential survival of individuals with different combinations of these variable characters.”…

Evolution, Does It Makes Sense? For hundreds of years the topic of how we got here today has been questioned, and formed into different theories that tell the history of life. The theory of evolution is the most thought out and elaborate way to look at how life started as only single celled organisms and evolved into many very complex species. Evolution is said to have started on a prehistoric earth after it had formed over 4.6 billion years ago. It took about a billion years after Earth was…

While finding food, the hammerhead shark uses its shape of its head to seek prey, which helps it to find food. That is one of the incredible abilities that animals have, to survive. They are called adaptations. The amazing pelagic zone is filled with many astounding animals, like puffer fish, great white sharks, seahorses, and many other mysterious creatures. The pelagic zone has frequent temperatures, lots of food, and very little pressure. The pelagic zone is in between the neritic zone and…

named Emma he supported him but would worry about what would happen if he did get what he expected. The five main ideas, as distinguished by biologist Ernst Mayr are evolution as such, common descent, gradualism, population speciation, and natural selection.…

1) What was the evolutionary significance of the wapH mutation? Do you think that the tests used proved this significance? The evolutionary significance of the wapH mutation in P.putida, this mutation doesn’t have a specific adaptive response to physical environment change. But wapH mutation occurred when wild-type P.putida detach and leaves the biofilm due to oxygen concentration level falls below a threshold. As wild-type P.putida leaves the biofilm it leaves behind uncolonized zones…

Throughout the history of life, organisms have been in a constant evolutionary flight to adaptations that better suit their surroundings, while becoming more complex in nature and achieving evolutionary hallmarks in the process. One such evolutionary leap is the transition from aquatic environment to terrestrial. One of the early terrestrial animals, the primitive amniotic synapsids are an important group of animals that pawed the way for endothermy, a significant adaptation that helped animals…

Ever since the beginning of time, natural selection has shaped our world. Natural selection, (also known as evolution), is the process of living organisms adapting and changing to survive in their natural environment. Many of the species that we know today have been involved in the process of evolution. Species don’t evolve like a flip of a switch, but are constantly evolving over a long period of time. As Darwin states, “Evolution occurs every 5,000 years”. There are several types of evolution…
