State 5 facts and 3 inferences Darwin used to construct the theory of Natural Selection. I'm confused I've listed overproduction, variation, and adaptation as the three inferences, but I do not know what to put for facts because what I've listed might belong under the facts category. Thanks!
Only when extensive genetic data became available were scientists able to definitively resolve the relationship between humans, chimpanzees and gorillas. Explain why the relationship between these three species was a particularly difficult challenge to solve. Important point. Explain why the relationship between these three species was a particularly difficult challenge to solve?? I don't really see that in your answer. I posted this question 3 times but answer given me wrong.

Explain some modern evidences of evolution. Please elaborate all and put definition and examples if ever. Please, thank you. Ps. This is actually my 2nd time to ask this same question.
please write your response to 1 of the options below. Ensure you include specific details of your ideas. Also, explain WHY you have chosen to highlight those aspects and make connections between the materials and your own previous knowledge and/or lived experiences. #1: Science is not done in a vacuum by singular hero-scientists -- it is a team effort. Which of these other scientists (i.e., not Darwin) highlighted in the lecture OR on the Evolutionary Scientists Today, Bio Anth Edition page did you find most surprising or intriguing? Why? #2: Evolution is not a mystery. We have observed many examples of populations changing over time both in the lab and in the wild. Which of these examples of Natural Selection in Action helped you understand how natural selection works the most? Why?
need a good answer.with explanation.Thanks 1- Which of the following species appeared earliest in the fossil record? Choices ( Homo neanderthalensis, Homo erectus, Homo sapiens, Australopithecus afarensis)
Hello, I need help answering number 29(INCLUDING THE SUB-PARTS) true or false questions. Pls and thank you! 29. A.)T / F - An increase in fitness due to natural selection depends on whether fitness is genetically variable in the population. B.) T / F - The first enzymes that evolved on earth were probably ribozymes (RNA that has catalytic functions). C.) T / F - The “Cambrian explosion” involved a great diversification of animal body plans that also included primitive chordates.
Are humans still evolving as species? Please think about the story of human evolution uncovered through genetic studies, and possible evidence that the evolution of our species continues. (essay type preferably 1100 words or more if possible..used as basis for academic research)
Hello, I need help answering number 34(INCLUDING THE SUB-PARTS) true or false questions. Pls and thank you! 34. A.) T / F: Both negative frequency-dependent selection and positive frequency-dependent selection act to maintain genetic polymorphism. B.) T / F: The mass extinction at the end of the Cretaceous caused the extinction of all non-avian dinosaurs. C.) T / F: Natural selection can occur without any evolution in the next generation if individual differences in the trait are not heritable.
Explain in short plz. Asap. Thanks Imagine a population of cacti living on an imaginary island called Plantopia. These cacti evolved to stop producing spines because there are no herbivores on Plantopia. Every year, a few cactus seeds are washed onto the shores of Plantopia from the mainland. There are many large herbivores on the mainland. (Tip: Try drawing the scenario to help you visualize it.) Name three mechanisms of evolutionary change ( 3 of mutation, natural selection, genetic drift, andgene flow.) that may be acting on alleles for spine production on Plantopia. For each mechanism, explain what effect it may have on spine production, and whether this change is adaptive or non-adaptive.
I need help answering the big font question from my teacher presentation: If evolution is true then why do new species seem to appear out of now ehere in the fossil record?
