3. 2. Application Sapiens existed on Earth for a relatively long time? Explain. Yes, 300,000 Years in fact Prior to the discovery of A. ramidus, could such a species be considered to be a "missing link"? Explain. How long would a timeline be (in kilometers) using a scale of 10 cm = 1,000 years? CUC Farth is characterized by the appearance of many new species and hu the persistence of some forms

Based on the maximum body volume of organisms preserved in the fossil record, body volume (as measured in log mm ) has increased over the last 3.5 billion years. The trend in growth over time is depicted in the graph where the x-axis is a measure of time in millions of years ago. Three boxes, each associated with a vertical dotted line that marks specific time points along the x-axis, have been provided. Place a check mark in the boxes to indicate when drastic increases in atmospheric oxygen are likely to have occurred. Body volume (log mm³) 4,000 2,000 1,000 Time (millions of years ago) 3,000 O Answer Bank ✓

In Oct 2022, a chilling discovery was made in Vuvatu, a country known for its extensive volcanic landscapes. Scientists found the remains of a large organism that had no resemblance to any current form of life on Earth. The organism also had no resemblance to any fossils ever found, including the very few fossils ever recovered from Vuvatu (fossils are rarely ever found in Vuvatu since volcanic landscapes are generally not conducive of fossilization). The world buzzed with the possibility that this was a crash site for an extraterrestrial body. An extensive study of the uncovered remains was conducted by many research facilities. Their conclusions regarding the organism’s features are listed below: Physical features: The organism has a surprisingly soft and malleable exoskeleton that reflects ambient light, creating mesmerizing patterns. In fact, the remains highly suggest that most of its body parts are soft and blubbery rather than rigid. Habitat: Given its relationship with…

Part I: Construct a phylogeny Below is a list of seven hypothetical, currently-living species (A-G), and eleven of their character states (i.e., traits). You will use these traits to construct your tree. Species Character states green еyes green no no egg wings claws hair A scales tail carnivore teeth spots horns layer green eyes green no egg В scales wings horns tail carnivore hair teeth spots claws layer egg layer green green no no scales wings claws tail carnivore hair spots eyes horns teeth no no no egg no no scales red eyes wings claws layer no tail carnivore spots horns hair teeth no no egg layer no no E spots red eyes horns scales claws tail carnivore wings hair teeth no no no live no F spots red eyes wings claws carnivore tail hair scales horns birth teeth no no no live no G spots red eyes wings claws tail herbivore hair scales horns birth teeth Assume that the extinct ancestor of this group, at the root of the phylogenetic tree, had the following features: no spots, no scales,…

Because mass extinction is a natural process that may facilitate evolution during the period of thousands to millions of years that follow it, should humans be concerned about the current mass extinction we are causing? Why or why not?

3. Module 1. Ecomarobs a. Observe the morphologies of the eight different lizard species. For now, assume that you have just discovered these lizards and you don't even know if they are 8 different species or 1 species or some other number of species. You just have 8 lizards, 4 from each island. b. Following the module, group the lizards by morphology. i. How many groups did you find?_ ii. What sorts of traits or characters did you use to group the lizards? c. Then take some more careful measurements as shown and regroup them if needed. i. Did your measurements match the reference set? ii. Compare Lamellae Count, Relative Hindlimb Length, and Relative Tail Length among your specimens, and regroup your species based on these characters. iii. Did your groupings change? If so, how? iv. Watch the video to see if your conclusions match those of Dr. Losos d. Now. If this is all you knew about these lizards, how many "species" would you conclude there are? e. What sort of species definition…

please explain  A drawback of the time hypothesis to explain the variation in species richness is that 1. Cannot account for algal diversity. 2. Fossils do not preserve well in the oceans. 3. Geological activity may interfere with species richness measurements. 4. It is not applicable to marine ecosystems because there was no glaciation in oceans. 5. Humans significantly modified marine environments.
