- The theory of evolution was controversial when it was first proposed in 1859, yet within 20 years virtually every working biologist had accepted evolution as the explanation for the diversity of life. Explain in at least 50 words why.arrow_forwardWhat is the origin of life or the main ancestor of all organismsarrow_forward“What is the origin of life or the main ancestor of all organisms?”, what would be your answer and why?arrow_forward
- Scientists classify living things in order to organize the astonishing diversity of life on Earth. Modern scientists base their classifications mainly on molecular similarities. They group together organisms that have similar proteins and DNA. Molecular similarities show that organisms are related. In other words, they are descendants of a common ancestor in the past. As we said earlier in our discussion, there are species that needs to be named and some are to be discovered. However, with the current environmental situation we have at the present (pollution, exploitation of resources, forest fires, and others), these species that are yet to be identified are being endangered and at the verge of extinction. As a matter of fact, the University of Turku reported last July 1, 2020 that there are 15 million estimated different species living in our planet but 2 million of them are currently known to science. Discovering these remaining species is important for them to be protected. Also,…arrow_forwardYou are studying the evolution of species.

Could this gene have evolved to confer some of the complex traits that we observe in modern animals, like multicellularity? Briefly explain.arrow_forward1. Design a cell/a system of cells using the following to show explicitly. Respiratory system, Energy generation, Forming tissue, and Maintaining order. 2.

- Which of the following illustrates the unity observed in organisms with a common ancestor? Flamingos and penguins are different colors. The gene for the human hormone insulin can be inserted into bacteria, and the resulting bacteria can use the gene to produce functional insulin. A robin can fly, but a penguin cannot. Fungi tend to absorb nutrients from other organisms, while animals consume their food. O Living organisms span a range of sizes.arrow_forwardCreate an informative essay showcasing the importance of evolution in our lives. With the changes in the structure of living organisms like plants and animals, how did these changes help the community of living organisms? How will the evidences found by several scientists be of help to us and to other organisms as well?arrow_forwardDoes evolution through natural selection produce “better” organisms in an absolute sense? Are we climbing the “Ladder of Nature”? Defend your answer.arrow_forward
