All living organisms are composed of one or more cells‚ and like any living organism‚ cells are made up of smaller structures that help them function. In the context of cells‚ these smaller structures are referred to as organelles and each organelle has its own unique function that has developed over time. While we are typically aware of how these organelles function‚ how they evolved raises several questions. The main model for how eukaryotic cells evolved over time is the endosymbiont theory. This

Ashley Andino October 2‚ 2014 Evolutionary Relationships in Mammals For this scientific argument‚ the research question was Which of these mammals are the most closely related? At first‚ my claim had stated “The mammals with more similar traights and characteristics were the ones that were the most closely related.” As my group and I looked deeper into the data‚ we had analyzed the different mammals and ended up with a final claim which was “The elk‚ cow‚ Caribou‚ the Pallid bat‚ and big eared

Evolutionary Medicine For many years‚ evolutionary principles have helped with many different aspects of the medical field. These principles have significantly helped with providing scientists with helpful information in understanding different illness‚ and issues that arise in the medical field. More specifically‚ the cooperation of evolutionary biology with modern medicine has helped with understanding antibiotic resistance and susceptibility‚ spread of disease‚ and development of cancer. I will

92\ a.1 Eukaryotic Cell vs Prokaryotic Cell All cells can be classfied into prokaryotes and eukaryotes. Prokaryotes were the only form of life on Earth for millions of years until more complicated eukaryotic cells came into being through the process of evolution.

16.1 All of Life is connected through its Evolutionary history Phylogeny- is the history of descent of organisms from their common ancestor. Groups of evolutionarily related species are represented as related branches in a PHYLOGENETIC TREE. - A group of species that consists of a common ancestor and all its evolutionary descendants is called a CLADE. Named clades and species are called TAXA. - HOMOLOGIES are similar traits that have been inherited from a common ancestor. - A trait that is

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane. The cell is the very smallest unit of living matter. All living things including plants and animals are made up of cells. Cells are made of atoms‚ which are the smallest units of matter. There are many different kinds of cells. The two kinds you are most likely to be familiar with are animal and plant

unique. The concept of evolutionary psychology explains that human behavior is largely influenced by their evolutionary ancestors through six theories and methods. Evolutionary psychology proposes that a lot of human behavior can be explained by the change of the physical and social environments through time. It argues that “much of human behavior is the output of psychological adaptations that evolved to solve recurrent problems in human ancestral environments.” (Evolutionary Psychology) The goals

INTRODUCTION: NULL HYPOTHEISIS: Mental disorders are not present in animals. HYPOTHESIS: As much as life has evolved‚ the relationship between animals and humans has remained very close to each other. If animals are‚ evolutionally‚ and genetically similar to humans; can they develop the same diseases we have today? Humans today

Strong evidence suggests that different types of photosynthetic cyanobacteria underwent endosymbiosis
