20+ years ago, the view of paleontologist and paleoanthropologist on the human evolution is linear/step-ladder where in one specie first then become extinct and then new species came out. Is this true? Explain well and give examples.
Structures in two different species may be similar because of either of two very different reasons. Describe these two reasons. You must use all four of the following terms in your explanation: homologous structures, analogous structures, convergent evolution, and divergent evolution
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?
Scientists often talk about the evidence for evolution. Using the five types of evidence listed here, explain how each suggests the occurrence of evolution: 1) structural homologies, 2) molecular homologies, 3) developmental homologies, 4) fossils (general) and 5) transition fossils.
Define the following terms: divergent evolution, convergent evolution, analogous structures, homologous structures
Main question I need for notes: If evolution is true then why do new species seem to appear out of nowhere in the fossil record?Please answer the question below the picture if possible, thank you.
This is a two part question, please write two separate essays, one for each part. Part 1: what is punctuated equilibrium and does the presence of fossils that are consistent with punctuated equilibrium mean that natural selection does not occur? Explain why or why not. Part 2: Does natural selection predict a gradualistic mode of evolution or punctuated equilibrium? Be sure to explain your answer.

Discuss the major events in the history of life on earth, starting from the origin of life up to the present day, highlighting key evolutionary developments and transitions. 2. What is the role of mass extinctions in shaping the history of life on Earth? How do these events influenced biodiversity and evolutionary trajectories?
The science of naming and classifying organisms is called______________. The related science of reconstructing anddepicting evolutionary history is called ______________.A group consisting of all organisms descended from aparticular common ancestor is a(n) ______________.
Some genetic studies suggest that the most recent common ancestor of Homo sapiens that lived outside of Africa spread from Africa about 50,000years ago. Compare this date to the dates of the fossil record. Can both the genetic results and the dates ascribe to the fossils be correct? Justify. PLEASE INDICATE A REFERENCE
Earth is about 4.5 billion years old. In order to characterize the events that happened in this very long time scale, scientists have developed the geologic time scale. Here, the age of Earth is divided into (1), which in turn divided into (2), and are further subdivided into (3). The geologic time scale is so-called since the different subdivisions are based on the fossil record.
