Big Idea 1: The process of evolution drives the diversity and unity of life.
Adaptation of an animal - Adaptation is a trait that evolves over time due to natural selection. This includes the evolutionary challenges the animal went through natural selection. This bird has an adaptation of a long, thin beak so it can reach through small cracks where other animals can't.
Analogous Structure - These are bones from different species that look the same but they also perform the same function. In this example, bats and birds both have wings that are used for flying.
Amniotic Egg - The Amniotic Egg is different from other eggs mainly because of the shell to protect it from death. Animals that come from amniotic eggs are dinosaurs, birds, turtles, lizards, and certain mammals. This is a picture of a spider tortoise, which is a type of turtle that came from an Amniotic Egg.
Bilateral Symmetry - This type of symmetry is where you can draw a line down the middle of something, and the left or right side are mirror images of each other . In this example there is a crocodile that displays bilateral symmetry with its right and left side of its body being mirror images of each other.
Chordate - These are animals that have four different categorizations notochord, hollow dorsal nerve cord, pharyngeal slits or gills, and a post-anal tail at some point in their lives. A good example of a Chordate is this fish which contains the 4 categories that a Chordata has.
Radial Symmetry - Radial symmetry is where you can cut something in half horizontally and the top and bottom cut out are symmetrical. Also it can be looked at as a cake, where if you cut it in fourths or eighths, all of the pieces are symmetrical. This is a member of the phylum Porifera and demonstrates radial symmetry.
Gastropod - These are more commonly known as snail and slugs. They are from the phylum Mollusca and their natural habitats are in gardens, woodlands, mountains, rivers, and mainly wet surfaces. The only difference between a snail and slug is the shell. There are also marine species of Gastropods with abalone, conches, and whelks. In this photo, there is a sea snail.
Genetic Variation - This is caused by three main sources: mutation, gene flow, and sex. Mutations can happen to anyone and a mutated may effect something physically or internally. Gene flow is the movement of genes from a population to another population and sex creates many different variations in genes due to crossing over and homozygous or heterozygous traits. This bird demonstrates plenty of genetic variation with its different array of colors and thick beak.
Gymnosperm Cone - These cones come from the seed producing plant called a Gymnosperm. These cones reproduce by the male cones producing pollen at the top part of the Gymnosperm tree, and releasing it. The female cone at the bottom receives the pollen and the zygote is fertilized and the seed is released. Female Gymnosperm cones are larger than the male cones.
Gymnosperm Leaf - These are the leaves of a Gymnosperm. A Gymnosperm is special because of its name. Gymnosperm means naked seed, which means that the seeds do not bear fruits. In these plants, reproduction is based off "airborne" not water transport, since the pollen is released into the air and the wind carries it to the female cone.
Homologous Structure - This is when two bones from different species look the same. Similar function does not matter for two structures to be homologous. For example, this dog's leg bones are similar as to a humans or a cat's.
Modified roots of a plant(potatoes) - Modified roots in plants are specialized to a certain plant needs. For example, these roots of the potatoes are modified to make new potato sprouts, store starch, water, and nutrients throughout the winter time which are essential for growth.
Modified leaf of a plant(poison ivy) - Modified leaves perform different functions like holding water, defense, or killing insects. Poison ivy leaves contain an oil called urushiol which causes rashes towards and irritation towards predators.
Tetrapod - Tetrapods are vertebrates with 4 limbs or legs. They include extinct and living animals. Tetrapods evolved from lobe-finned fishes. This leopard has 4 legs.
Gnathostomes - Gnathostomes are vertebrates with jaws. 99% of vertebrates are gnathostomes. Monkeys have jaws so that's why they are gnathostomes, their jaws are actually similar to humans as well.
Modified stem of a plant - A modified stem of a plant can be used to retain more water than a normal plant, have thorns, or grow below the ground and store nutrients. This plant has a stem with thorns to protect itself from grazing animals.
Artificial Selection - Artificial selection is where two or more different species are chosen to mate with one another or a certain species attributes are selected specifically. This occurs for a variety of reasons such as to make a certain species look better, taller, stronger in a certain area or to create a whole new species. Broccoli is a type of vegetable that comes from a wild mustard seed and farmers chose to suppress flower development in the wild mustard seed so they could come up with this new crop, Broccoli.
Adaptation of a plant - Plant adaptations are gained through natural selection and help them live in their habitat. Certain adaptations are why a certain plant may not live in another habitat or it will die. This orange tree has adapted so it grows oranges.
Deuterostome - This is a super-phylum of animals that are determined by their early development. Deuterostomes first opening is their anus. The phylum Echinodermata is a branch of this super phyla. This is an example of a sea star which is apart of the phylum Echinodermata. Deuterostomes are the opposite of protostomes whose first opening is the mouth.
Angiosperm - Angiosperms are flowering plants. So as you see in the photo, there are 4 orange,reddish flowers.
Radial Symmetry - Radial symmetry is where you can cut something in half horizontally and the top and bottom cut out are symmetrical. Also it can be looked at as a cake, where if you cut it in fourths or eighths, all of the pieces are symmetrical. This is a member of the phylum Porifera and demonstrates radial symmetry.
