What phylum have true coelom and are deuterostomes?
The phylum that have a true coelom and are deuterostomes are the phylum Chordata. This phylum includes animals with a notochord, dorsal nerve cord, pharyngeal slits, and post-anal tail at some stage in their development. Examples of Chordata include vertebrates such as fish, amphibians, reptiles, birds, and mammals.
Are Humanzee chimp-human hybrids Possible?
That is hard to answer with certainty. Prof. Robin Bernstein of George Washington University says that it might be possible in a lab setting, but there are three barriers to this happening in the wild: 1) humans and chimps would not normally look at each other as mates; 2) the biological mechanisms of human and chimp sexual reproduction are not exactly the same; and 3) There are great differences at the chromosomal level. I will go over each of these. First, animals tend to mate with their own species. This is because they are genetically programed to detect certain bodily attributes or hormones that make the males or females of their species attractive. In addition, species that are active in different areas tend not to come in contact with each other. So the chances of a male chimp and a female human or a female chimp and a male human finding each other attractive and mating in the wild is very slim. However, chimps raised as human children have been shown to be attracted to humans. See the question "Could a chimp mate with a human?" for more information.
Second, although both have similar reproductive systems, they are not exactly the same. For instance, chimpanzee penises are very long for their body size, but they are carrot-like in nature (i.e., it is wide at the base and tapers to a point). Human penises, on the other hand, are wide at the base and have a wide head. This means a chimp penis might not be rigid enough to reach far enough inside a human female to implant seed. The human penis might be too big to reach far enough inside a chimp female to do the same. It is important to mention that humans have forward-facing vaginas, while chimps have backwards-facing vaginas. Humans can have sex face to face, something that chimps can't do. Considering that chimps must mate in an awkward "doggie style," a human male might have problems orienting himself. The male chimp may have similar problems.
Third, chimps have 48 chromosomes (2 pairs of 24) and humans have 46 (2 pairs of 23). It is known that human chromosome 2 is simply a fused version of the chimp chromosome, which accounts for us having 2 less chromosomes. Animals with different chromosome counts can't usually mate, but there are a few instances where they have. For example, horses have 64 (2 pairs of 32) and a donkey has 62 (2 pairs of 31), but yet they are able to produce a mule. Since the mule gets an unequal number of chromosomes from both parents, it is born sterile due to genetic abnormalities. Therefore, if a chimp-human hybrid could ever be brought to term, a male specimen could never reproduce. Yet, there is evidence that human ancestors and chimps might have interbred in the past.
The oldest fossil associated with the human lineage is around 7 million years old. This means the joint human-chimp ancestor probably lived around this time. Yet, genetic chronology shows that the split between the lineages happened around 5 million years ago. In his article "Two Splits Between Human and Chimp Lines Suggested," science journalist Nicholas Wade describes genetic research that reconciles the difference by positing the separate human and chimp lineages might have continued to breed and later split for a second and final time. Genetic chronology shows that the X chromosome in the human and chimp lineages split over a million years before the other chromosomes. Dr. David Reich of Cambridge, the head researcher on the project, suggests this could have been caused by hybrid females interbreeding with chimpanzees (since hybrid males would not have been able to reproduce). In addition, he further suggests that this interbreeding could have hastened human evolution since it would have allowed us to better adapt to the new environment of the African savannah. Paleoanthropologists like Dr. David Pilbeam of Harvard are not quick to accept the information since genetic chronology only provides "relative ages, which are translated into real time by reference to a timescale established by early ape and monkey fossils." Further research is needed to determine if the hybrid theory is correct.
The Russian biologist Ilya Ivanov tried for 4 years from 1926 to 1930 to produce a Humanzee in a lab setting. He initially gained permission from the French government and backing from the Soviet government in 1925 to start such experiments in Kindia in Guinea (northeastern Africa), but none of the chimps assigned to him a year later where sexually mature enough to carry children to term. He then relocated to the Guinean capital of Conakry in late 1926 to capture his own specimens. He artificially inseminated three female chimps with human sperm in early and mid-1927, but none of them became pregnant. After returning to Russia in 1929, he gained permission and backing from the Soviet government to conduct human trials. But after the 1929 election changed the USSR's power base, Ivanov's experiments were stopped and he was eventually arrested and exiled. To my knowledge, no one has tried (legally or otherwise) to create a Humanzee since then.
Barring the natural barriers mentioned above, I believe there might be a psychobiological explanation for why Ivanov's early batch of chimps did not become pregnant. Ivanov captured wild chimps and then confined them to cages. One was even shipped from Africa to France by boat. Prof. Roger Fouts mentions in his book Next of Kin: My Conversation with Chimpanzees (1997) that such stress can cause adverse effects in chimps like hair-pulling and self-mutilation. Stress-induced chemicals like alpha-amylase have been shown to reduce a human woman's ability to become pregnant because it slows the descent of the egg. So it's possible that the stress from being confined to cages may have kept the chimp egg and human sperm from meeting. If he had used human-raised chimps who lived in spacious modern facilities, he may have had a better chance of succeeding. There is no telling what would have happened if the human trials were carried through.
Why was Goodall surprised to observe the chimpanzees eating the pig?
Goodall was surprised to observe the chimpanzees eating a pig because she had not previously seen them hunt or eat meat, which was not a typical behavior for chimpanzees at that time. This observation challenged the existing belief that chimpanzees were strict herbivores.
Do chimps look for fleas in each others heads?
Yes, chimpanzees engage in grooming behaviors where they pick through each other's hair to search for fleas and other parasites. This helps to maintain their social bonds and hygiene within the group.
What type of cells does mitosis result in?
Mitosis results in the production of two daughter cells, each containing the same number of chromosomes as the original parental cell. These daughter cells are genetically identical to each other and the parent cell.
Why do some people not feel an earthquake but a seismograph does?
Some people may not feel an earthquake because they are not in close proximity to the epicenter or the ground motion is not strong enough at their location. A seismograph, on the other hand, is a highly sensitive instrument designed to detect even small ground vibrations, allowing it to record seismic waves that may not be perceptible to humans.
That depends on what you mean by "mean." Chimps are wild animals, so their behavior is obviously going to conflict with what is considered normal decorum by human standards. Males are very territorial, meaning they are willing to harm any individual that they deem a threat. They have even been known to kill and eat the babies of their own species. However, they are gentle to those within their family units. Chimps have built in social mechanisms for reconciliation. That is, if they get into fights, they will eventually mend the rift through hugging, kissing, food sharing, and grooming. Bonobos, a close cousin of the Chimp, even have non-reproductive sex in order to calm nerves.
Did four of the chimps die that Jane Goodall was studying?
Many of the chimps that she studied died. This was due to injury, disease, or just old age. For more, see her book The Chimpanzees of Gombe (1986).
How did Jane Goodall become successful?
Jane Goodall became successful by dedicating her life to studying and advocating for chimpanzees and their conservation. She overcame challenges and obstacles to become a renowned primatologist, making groundbreaking discoveries about chimpanzee behavior in the wild. Her passion, perseverance, and commitment to her cause have helped her achieve global recognition and influence in the field of conservation.
What does it mean when human DNA is similar to chimpanzee DNA?
The similarity between human and chimpanzee DNA (around 98%) indicates a shared evolutionary history between the two species. This common genetic heritage reflects a close evolutionary relationship and suggests a relatively recent divergence from a common ancestor.
Is a cold blooded animal more cruel than a warm blooded?
No. I think you're thinking of cold hearted-- but even that's just a saying. Warm blooded animals can be cruel and cold can be too, it doesn't matter their blood.
What year did Jane Goodall study chimps?
she started research at the age of 19 when her life dream was starting to happen. she then went to Kenya to visit a girlfriend. even though she had loved animals before she even turned 1, she had a best friend, who was actually a dog. Jane Goodall was born April 3, 1934 and is still alive today
What did Jane Goodall like to do when she was young?
Jane Goodall enjoyed spending time outdoors and observing nature, particularly animals. She had a particular passion for chimpanzees, which eventually led to her groundbreaking research in primatology. Goodall also liked to read books about animals and explore the countryside near her childhood home.
Does bread mold undergo mitosis and meiosis?
Bread mold undergoes both mitosis and meiosis during its life cycle. Mitosis is responsible for growth and asexual reproduction, while meiosis is involved in sexual reproduction to produce spores for genetic variability. Mold spores are then released to spread and germinate into new mold colonies.
How long did Jane Goodall study chips?
Jane Goodall studied chimpanzees for over 55 years, starting in 1960 when she first arrived in Tanzania to study the behavior of wild chimpanzees in Gombe Stream National Park. Her pioneering research has significantly contributed to our understanding of chimpanzee behavior and their social structures.
What do Chimps express when smiling?
Although they act very similar, Chimps and humans do not always have analogous behavior. Smiling in primates is usually a sign of nervousness or anxiety. For example, a Chimp faced with a hostile alpha male will often smile in their presence until they are reassured that no harm will come to them. This anxiety can be alleviated by the alpha simply putting their arm around them.
What cells produced after meiosis?
After meiosis, haploid cells are produced. These cells are called gametes – sperm cells in males and egg cells in females. These gametes have half the number of chromosomes as the parent cell.
What name is given to the new cells formed after mitosis and meiosis?
the cells formed by mitosis and meiosis are called daughter cells.
What was the name of Jane Goodall's favorite monkey?
Jane Goodall's favorite chimpanzee was named David Greybeard. She developed a special bond with him while studying chimpanzees in Gombe Stream National Park in Tanzania.
How did Jane Goodall effect how you live today?
Jane Goodall's work in primatology and conservation has inspired many to care for the environment and all living creatures on Earth. Her dedication to understanding and protecting chimpanzees has raised awareness about the importance of preserving wildlife and their habitats, influencing how people view their relationship with nature and the need for sustainable living practices.
There are many animals that are ectotherms (the term cold-blooded is not used as frequently because their blood temperature can often be much higher than that of other animals).
These animals include; insects, reptiles, amphibians and fish.
The genitals of the female Chimpanzee balloons into a giant pink swelling during her time of estrus. This is when she is most susceptible to becoming pregnant. The pink coloring and smell of hormones lets potential suitors know that she is receptive. The alpha male usually gets to mate first, followed by those who are aligned with him. Some younger males must mate in secret in order to avoid a fatal beating or exile.
As for males, different communities use different methods. One uses something known as "leaf cutting." They do this by stripping the membrane from a leaf stem with their mouth. The noticeable "zipping" noise attracts the attention of estrous females. Males sometimes bypass this by just shaking tree limbs. Others sit on the ground with legs apart in order to display their erections.
