The zoo is a wondrous place where you go to see a distant relative. Yes that may sound weird but the animals there may be related to you but definitely not close so don’t panic. The animals have evolved over time to become very far distant relatives. Species do change over time and we can see this through the competition, adaptations, and environment changes. We can also see this throughout history with many fossils and common traits among organisms. The competition between organisms forces them to adapt to their environment and this occurs throughout history, so they all tie together.

Competition allows only the most fit species to pass on their genes. In the bird beak lab, the chopsticks were unsuccessful at picking up seeds while the tweezers were successful and would survive over the chopsticks and pass on their traits. Competing with other organisms for a desired food or object can cause the less fit to die off and not pass on genes. During the bunny lab, another example, the long teeth bunnies survived longer over the short teeth bunnies. This occured due to the competition of food, which the long teeth bunnies were able to chew more efficiently, making them survive. …show more content…
For example in the stickleback fish lab, they lost their spines to survive in the less predatory waters. This allowed them to lose the armour and become faster to survive in the lakes. During the bunny lab, the bunnies mutated and then adapted to become fit in the environment they live in. The bunnies adapted to the color, food, or predators which allowed them to survive in the environment rather than die off. The NOVA lab demonstrated that animals are closely related through a common ancestor but have adapted to become different and survive. Organisms with vertebrate have ancestral ties, but adapted to survive in the different environments so they grew to be different. Adaptations occur to benefit organisms in their

Anatomical And Postcranial Change

Evolution is an important part of understanding how humans have changed over time and how we have become who we are in modern day. Changes are mostly observed in our anatomy, separated into cranial and post-cranial differences, and are able to tell us how we were able to live and survive as the primitive species we once were. The anatomical changes in the cranium can give us clues to our brain size, and diet restrictions. The size of the skull increased over time as well as the size of our brains. Primitive…

Introduction to Evolution Essay

there are too many for the available food, at which time they will compete for scarce resources. This got Darwin thinking about natural selection and the concept of biological fitness, and ultimately, to how natural selection, coupled with spontaneous mutations, could shape the characteristics of the survivors through succeeding generations, and how this could account for the diversity among the species and their evolution over sufficient periods of time.

Charles Darwin Essay

Evolution is something that I’ve always been interested in and something that sciences leans back on time after time. Everything thing that scientists talk about or studies about can be linked back to evolution. He makes it apparent in his essay and how fundamental natural selection is. His ideals on natural selection explain everything that has to do with species and environment. How they interact and how fragile each part of them really is. Darwin makes it very easy to believe in what he is saying and…

Change may also be triggered by competition, for example, competition…

The Misconceptions In Charles Darwin's Theory Of Evolution

science, rarely did scientists go against the churches view. In 1859, a man named Charles Darwin published his book-origin of the species- that went against everything the church believed; Charles Darwin presented his theory of evolution. Evolution has many misconceptions such as: explaining what evolution is and how evolution works, what scientist believe today and how evolution is used in today’s medical field. First, most people believe that evolution is the accusation people came from monkeys…

Examples Of Natural Selection And Speciation

Natural Selection • The process where species adapt to their environment. • Driving Force = Competition for Resources • Involves Populations and their Gene Pools • Gene Pool = All of the Genes/Alleles in a population • Differential Reproduction results in loss and gain of population characteristics • Shifting of gene pools occurs due to differential reproduction = biological evolution.

Biodiversity is the variety of the earth’s species, the genes they contain, the ecosystems in which they live, and the ecosystem processes that sustain all. It’s important because it’s a vital renewable resource. A species is a set of individuals that can mate and produce fertile offspring. Insects are pollinators, which help sustain life on earth. Biomes are large regions with distinct climates and a set of species that are…
