What do you conclude from the study of embryos?​

We can get a glimpse into an organism's evolutionary history through embryology. As an illustration, consider terrestrial vertebrates, which include mammals, birds, amphibians, and reptiles. There are numerous parallels between fish embryos and other animal embryos when we examine the early stages of the development of various groups of animals. All of these animal groups have gill arches in their developing embryos. These develop into functioning gills in fish embryos. They go on to develop into the morphological structures that make up our ears in the majority of terrestrial animals. This helps us understand how certain animal traits may have evolved from more basic ones. Cases like these add to the body of evidence showing that lobe-finned fishes are the ancestors of terrestrial mammals.

<h2>How does embryology prove evolution happened?</h2>

Embryology offers no proof. The descriptive study of embryos is known as embryology. It has been discovered that embryos from all species have parts that should naturally belong to less advanced organisms. By the time the embryo develops into a fully formed live being, those structures have either vanished or changed into something more adapted to the particular environment. Because the ancestors of the species whose embryo we are investigating truly possessed such qualities and made use of them, we refer to them as atavistic features, from the Latin term for forefather. These traits are numerous. I'll name one. An embryonic human resembles an embryonic monkey almost exactly, down to the tail. Human genes guarantee (nearly invariably) that the tail resorbs, leaving just a little remnant with five tail bones, the coccyx, whereas the genes of the monkey ensure that it is still present at birth. Human embryos, as well as monkeys and many other animals, feature fish-like gill clefts. In our situation, they were born as more beneficial organs.

Therefore, embryology detects phenomena that call for justification. They would just be bizarre if they weren't. Every creature's embryology may be thoroughly examined to build a comprehensive picture that is perfectly compatible with evolution. That is but one piece of the puzzle of findings and information that support the hypothesis (i.e., explanation) of evolution.

To be fair, I should point out that there are alternative hypotheses that might account for the embryological findings as well as the variety and at the same time linear similarity of all living things, whether ancient and modern. Accepting these alternative explanations allows you to forget about learning anything and skip over years of fruitless inquiry in the fields of embryology, paleontology, biology, and anatomy. It also greatly simplifies the process of comprehension. All you need to do is put your trust in the scientifically illiterate authors from two centuries ago who, through no fault of their own, may have known nothing about biology, anatomy, or physiology because those fields didn't even exist at the time. As a result, they could have observed nothing and conducted zero research.

That does however require you to understand that the tens of thousands of scientists who have carried out all the work over the past 200 years have all been frauds, and that there is a massive global conspiracy devoted to disseminating lies and misinformation in order to enrage a small American sect known as creationists. even if the majority of those scientists practice religions similar to those of everyone else. Why? It must be to exact revenge on those hateful Christians, who have undoubtedly caused them terrible, unnamed suffering.

Answer: Nervous system, skeletal system, muscular system. The nervous system control the muscles and the skeletal system helps to support those muscles.

Explanation:

The nervous system consists of a set of cells specialized in conducting electrical and chemical signals, called neurons, and glial cells that are supportive. <u>The nervous system picks up external stimuli from the environment or signals from the organism itself (internal stimuli), and this information is transmitted by nerves to the brain, where everything is processed and a signal is emitted that causes the contraction of certain muscles. </u>

The nervous system is divided into central and peripheral systems. The central nervous system comprises the spinal cord and brain, while the peripheral nervous system comprises the nerves that connect the central nervous system to the body. Within the peripheral nervous system, there is a sensory (afferent) nervous system responsible for incorporating information from receptors (such as the eyes, the skin for touch, etc.), and a motor (efferent) system that carries the information to the muscles.  

From the functional point of view, it is also differentiated into somatic and autonomic system. The somatic nervous system consists of neurons that control voluntary actions, while the autonomic nervous system is responsible for involuntary functions. And within the latter group are included the sympathetic nervous system (which is activated in situations of danger to stimulate many organ functions that cause a rapid response), the parasympathetic (which is involved in the regulation of several organs and its action is opposite to that of the sympathetic nervous system) and the enteric nervous system in the gastrointestinal tract.  

The muscular system is a set of muscles that can be controlled voluntarily, if we refer to skeletal muscles. <u>Their main function is mobility, an action that takes place when stimuli from the nervous system provoke the contraction of the muscle fibers</u>. There are three types of muscle tissue: skeletal, smooth and cardiac, and all of them are able to contract but they differ in certain characteristics, location and the way in which the contraction is regulated, which can be voluntary or involuntary.  

Muscle tissue receives electrical impulses from the nervous system and responds to them by generating a contraction movement. The neuromuscular junction plate is the connection established between a motor neuron and a muscle, by means of which the neuron transmits electrical impulses to the muscle fiber and between them there is a space called synaptic cleft. When a nerve impulse called action potential travels through the axon of a motor neuron, the neurotransmitter acetylcholine is released into the synaptic cleft, which binds to the muscle cell membrane and causes it to alter its membrane potential causing a depolarization that triggers contraction.  

Finally, the skeletal system consists of a rigid structure formed by bones, and has several functions such as mechanical support, maintenance of posture, makes possible the bipedal position and protection of vital organs. The joints between two adjacent bones, called articulations, make muscular movements possible. <u>In addition, the bones serve as insertion sites for the tendons of the muscles, which allow movement </u>that is controlled by the nervous system and carried out mainly by the muscular system.

So, the nervous system control the muscles and the skeletal system helps to support those muscles.

zzz [600]

Answer;

-Evolution by natural selection

-The theory of evolution by natural selection states that organisms that are better suited for their environment will survive and reproduce, while those that are poorly suited for their environment will die off.

Explanation;

-The theory of evolution encompasses the well established scientific view that organic life on our planet has changed over long periods of time and continues to change by a process known as natural selection.

-Natural selection is the phenomenon that some traits confer a reproductive advantage (fitness), resulting in (a statistical expectation of) that trait increasing in the population over time (evolution).
