a layer of any material esp one of several parallel layers. What is strata in biology?Д«iology a single layer of tissue or cells. There are many varieties and different kinds of rocks that can also have layering in them for instance the volcanic rocks but the word strata are reserved for sedimentary rocks. The term rock strata refer to the stacked-up layers that are often placed horizontally of the sedimentary rock. In geology and related fields a stratum (plural: strata) is a layer of sedimentary rock or soil or igneous rock that was formed at the EarthвЂ™s surface with internally consistent characteristics that distinguish it from other layers.

Why do you think that? Yes I do think they have a common ancestor, because they had needed to evolve, mutat, survive, and reproduce, in order for their species to be a live. I think they are closely related because they have similarities in traits and the way their positioned. They both have a tail, they have red spots on them, their head shape is similar, their hands and feet looks the same, they are in the same position. Which two embryos are the most closely related? Why do you think that? I think the Mouse, and the human embryo are closely related. The elephant isn't in the same position as the other embryo, like the other embryos hands, feet, and head are closely together. The mouse embryo's eyes are white in the middle, and black around, the others' eyes are blue or red. You can see that the dog embryos ears look already formed, the rest don't. What differences do the embryos have? The differences the embryos has is the the human embryos head is bigger than the others. The human embryo and mouse embryo both have tails. The human and the mouse embryos have red spots on their body's. The elephant, and dog's eyes look the same colorwise. The human, dog, mouse, embryos hands are in the same position also their hands and feet look the same. What similarities do the embryos have? The similarities the embryos have is the human, and dog head shape looks similar. Just like I think the Ancient Crocodile evolved to the Modern Crocodile.

Do you think they have a resent (1,000,000 years ago) common ancestor or do you think their common ancestor is older than that? Why do you think that? I think they do have a common ancestor because the Ancient Crocodile had to evolve. They could have evolved and mutated on how they look today and even though their are some things that are different, they have the same traits and the Ancient Crocodile could have mutated to the crocodile that looks like today. The ancient crocodile's body looks longer, it's snout looks longer, and it looks skinny. Based on these similarities, what can you conclude about these animals history? Yes I think they're related even though the modern crocodile looks smaller, the snout looks shorter, and the head looks wider. I think the long tails were used to hurt the prey by the crocodiles wiping their tail at them. Explain what the trait is and what you think the trait was used for.

One trait that both fossils have in common is they have long tails. Find one feature (trait) that BOTH fossils have in common.
